https://en.m.wikipedia.org/wiki/Tim_Sweeney_(game_developer)
Founder and CEO of Epic games.
He has a history of whinging about Windows, and when suggestions of supporting Linux come up, since it's what Valve is doing to ensure they aren't trapped in a mono-system, Tim is argumentative in a bad faith way.
Previous discussions about Epics anti-Linux behaviour, but unfortunately the Tweets have since been deleted.
