Can confirm, Garry is a total fucking asshole, who also sucks at coding and software engineering.

He deleted the old Facepunch forums because they were absolutely chalk full of him being a dick needlessly, being told about bugs and problems and better ways to do things, and mocking and banning those people... when they were correct.

He got tired of deleting threads and banning people who functionally developed the game for him, for the purposes of being able to gaslight others, so he just nuked it all.

I was a part of the GMod community since before it was sold for money, when it was a ripoff of JBMod... he has always been like this, and he has never changed.

EDIT:

The Anti Cheat thing on linux and rust is particularly a good example of this kind of incompetence and asswipeitude:

Rust uses Easy Anti Cheat.

... Easy Anti Cheat supports linux, there are a fair number of games that work with EAC, on linux.

What Garry cannot do, is architect a game in such a way that... EAC can work with it, on linux.

... I learned programming by way of creating both game modes ... and exploits... for Garrys Mod.

... I was 16, and I could defeat various parts of Garry's attempts at secure netcode (rather, the framework Garry uses to interperet/wrap/encapsulate Source netcode).

Some 'friends' I knew... were even better at it than I was.

Garry is not good at programming.

But according to him, you're the idiot if you point out any problems with anything he's ever created.

There's a review on Steam right now, for Sandbox.

Sometimes, you join a custom gamemode?

Time to download 10 gigabytes.

... there were viruses that propogated through Steam itself, where Garry's Mod... using a similar way of grabbing files... was the attack vector.

That Valve themselves had to step in and fix, because they didn't imagine that anyone would make such obtuse and dangerous usage of the Steam/Source protocols, as Garry just... thinks is fine.
