You forgot the "basement dwelling gatekeepers", there are the ones whose minds never left their parents basement and whose social skills aka lack thereof is evident in their gatekeeping.

Their way is the only correct way and Linus has actually no idea how to run Linux, hardware manufacturers don't know anything about their products, anyone using not their service of choice is automatically an idiot and if you don't know how to compile xyz yourself by using a self taught technique you really should get off the internet right now.

Often their advice is inefficient, sometimes it's outdated and some even blatantly lie (had one boast in a discord that he has a myriad of secret user accounts where he intentionally gives bad advice to a FOSS product he hates).

Some also intentionally make whatever the goal is appear much harder in an effort to look smarter (that behaviour is often found in the professional world as well*)

They are the cancerous sore of FOSS and social media,imho.

PS: Anecdote: I work in healthcare,not IT originally. Everything I know is self taught, therefore. Started a new consulting gig and one of these guys, very much a "IT gatekeeper" always made the company he worked for think it takes a massive effort to install a certain product. Which made everyone's life much harder because yes,he did install it, but he manually compiled it which took him weeks at a time, while his other work piled up. So they tried not to use this essential product whenever possible and worked their way around it.

I came there, saw that I needed said product and had it installed within 20min. The CEO sat right next to me and was stunned. "You prepared that, right?" "Uhm,no? You can just download and install it like this?"

IT-Gatekeeper was asked to join the meeting asap and told to explain why they need so long. His only excuse was "I need to review all the code" - which he did diligently, but he always reviewed ALL the code not only changes, according to his notes.

I made the mistake of saying to myself a bit to loud "but if you compile that stuff yourself then you are liable if it breaks,if you use the advised packages from the manufacturer they are"(medical device law can be interesting). IT-Gatekeeper exploded and screamed at me how I have no idea how IT works,etc.

He was let go shortly after that.
