Okay then, I'll ask you this. What can you demonstrate that you have prevented extremely large corporations or the government from doing with your information by replacing some of your services with "privacy-focused" services? Do you really think that, say, the NSA and Amazon don't know you better than you know yourself regardless of your efforts? What do you think is prevented by using some isolated services while you still, no doubt, have most of your data being collected and used by other things?

Could you prove that your life would be any different if, for example, every single piece of information Meta has about you that you don't know they have were wiped off of their servers? Or that anyone here's life would be different?

The only thing I could imagine you could demonstrate is that targetted ads could be "worse". Which is a non-answer, many peoples' ads are completely inaccurate regardless, and ads aren't such a good metric to base the government's or Nvidia's or whoever's access to your data off of.

Fact of the matter is is that, unless you're mega-Amish, your efforts to prevent powerful entities from collecting your data are meaningless, they don't work well, and without strong privacy laws it will forever be that way unless everyone suddenly agrees to only use FOSS user-friendly products and all the ISPs are replaced by good guys. I guess some people here have spent thousands of dollars and hours in an attempt to keep their privacy in their own hands in spite of that, so they have to convince themselves it does work... I don't blame them, government corruption & corporatism has made me desparate before too.
