Because that's not how professional software development works. You don't actually get free programmers because most of the time your customers are not techy people.
E.g. if I develop some special software for dentists or whatever, and I open source it, all I get is that someone else builds the code and distributes it for free so I can't easily sell it anymore.

Can someone rip your work? Yes. Is that really an issue? No. Just stealing the code changes nothing, the person needs to invest money to continue build it themselves. The original developers will always be at an advantage since they know the code base. The fork (the new version) also won’t benefit from any of the changes by the original developers, or they need to carefully copy them over. If the hostile fork is also open source then it doesn’t matter since you can just take their changes if they are good. Making it mutual.
You can also use licenses that forbid the closing of the source. Doesn’t stop real thief’s, but it gives you a tool to stop it and also anyone who ignores a license like that is also generally not very competent.
Not necessarily. The original developer might know the code base better, but the hostile fork needs no development cost.
The 3D printing industry is a really good example of something like that. Take for example Marlin. That's the firmware that runs on the vast majority of 3D printers. It is open source and thus freely available.
Many 3D printer manufacturers just download a copy of Marlin, change the logos and slap it onto their printer. They are never going to update it, because Marlin is great as is and most customers won't ever update it anyway. So the 3D printer manufacturer has a development cost of maybe 1-2h to dial in the config and replace the logos. Compared to the developers of Marlin, who spent whatever the time equivalent to 19691 commits is. Also, the 3D printer manufacturer earns money from the sale, the Marlin devs don't.
Or take a look at e3d, who recently stopped open sourcing their hardware. They created the E3D v6 hotend, which is by far the most common hotend to this day. The issue is, most people don't buy an original E3D v6, which costs ~€50-70 (the more common 1.75mm version), but instead they buy the cheap €15 copy from Amazon or the €5 version from Aliexpress.
Again, the copyists might not have the expertise that e3d put into their work, but they know the exact dimensions and the material that needs to be used, and they just make a perfect replica. No research costs, only manufacturing, and be done with it.
Open source is only sustainable if you get your money for developing, not for selling the product. So for open source to work, you need e.g. a Patreon or cooperate sponsorships to fund the development, so that after development is done (before any product is sold) you got your money.

Sorry, but your arguments are seriously flawed, and you calling everyone uneducated who doesn't follow your flawed argumentation is honestly insulting.
Many intellectual properties are hard to create but easy to copy, and the whole point of an open source project is to make it easy to replicate. If you want to stop others from building your project, open sourcing the design files, manuals, source code and project documentation is not the right way to go.
I actually would not buy a 3D printer hotend from Amazon or Aliexpress. Not only because that would be utterly irresponsible to buy manufactured e-waste when our landfills are already overflowing; but because that’s actually how you stay poor: investing into a high quality product will relatively yield better results for a much longer time, and will end up costing you dramatically less in the long run.
This is just an utter misunderstanding of the whole situation.
Designing and making a 3D printer or parts of one are two very different things. Designing means you need to have a good hardware designer that spends a lot of time trying to find the best geometry and materials for the job. Making the parts means you need to have a good machinist and good tools for that.
Most of these cheap clones are made by really good hardware manufacturers. For example, Trianglelabs hotends are on the exact same level of quality as an original e3d part.
So buying clones is not e-waste at all (at least not more than the original parts) and the original parts are (to the consumer) mostly just really expensive versions of the same thing. Which anyone educated in that field would know.
High price doesn't equate quality at all. Just ask the guys who are currently floating around the Titanic.
I actually would not buy a 3D printer hotend from Amazon or Aliexpress.
Btw, e3d does sell on Amazon and Aliexpress as well. So that point is totally moot.
Imitation is the sincerest form of flattery.
Finally, companies don't care about flattery. Flattery doesn't pay bills or earn profit.
Because it's a lot of work to check that repos contain no confidential information, and to sync internal and external repos if there is a need for some internal-specific stuff. Especially when most software is very specific - e.g. I work in data pipelines for accounting and our logic is specific to our accounting processes.
I think some industries like video games should absolutely do it though, where the turn-around time on products is much faster. The main objection is that it just helps competition (and asset-swap scammers, etc.) but I think that's missing the bigger picture of more tooling and assets helping to grow the industry and labour pool as a whole.

Because they can make more money by walling the garden.
I'm not sure they are. I bet lots of them use Linux servers, Solr, several open source databases and so on. I think it's mostly the small and medium companies who are afraid of missing support and stuff.
The big companies just don't like selling open source to their customers. Or getting them too close to the concept of it.
The issue is there are a few ways of doing open source wrong.
The biggest way to do it wrong is to try to sell the open source product while giving the source away for free. Because that means, there will be someone else who just takes the source and copies it with no or only minor changes (e.g. replacing logos and names).
The copyists always have an huge competitive advantage, since they don't have to pay for development. Especially for software, development makes up almost all of the cost, so that essentially means they can give away the product for almost free and still make a profit. Or they are open source spirited themselves and give it away completely for free, like CentOS.
Sure, Red Hat can actually develop features that customers are asking for, which CentOS can't really do, since they can't influence Red Hat's roadmap, but considering that Red Hat is asking for $350 for a server license, a free-and-good-enough alternative seems to be the better option for many.
According to Wikipedia, CentOS is much more popular (or at least was in 2021) than Red Hat Enterprise Linux.
So to do Open Source right, you need to make money from developing it. This is e.g. how the Linux kernel works. They don't sell the kernel, but instead many companies fund kernel development either financially or through dedicating developers to that project. There are e.g. a lot of devs employed by Microsoft who are working on the Linux kernel.
This gives these companies the ability to prioritize what features/bugs should be worked on.
But this model doesn't fit every product and thus not every product can be financially viably done in Open Source.

I personally think the best way to do open source is to do it as a hobby, and not hope for profits off of it. Open source is fundamentally programmers taking control of their field's means of production, and the last thing I want to see is corporations co-opting that moreso than they have.
This is the main reason everything I release is AGPL unless there is a strong reason against it: Corporations won't use it.
