Team Fortress 2 updated with a whole bunch of fixes thanks to the community having the source code

It's not "open-source" either, so neither of these communities fit.
Yes, I am aware that the game code can be modified under a custom license now, but that does not extend to the game engine and the license is not OSI compatible, so calling it open-source would be highly misleading.
Many games that can be modded have the source for the game code available 🤷
