I know we happen to be a minority, but given how much valve has done for linux gaming, I'm happy to vote and support them with my wallet.
For reference, before they started giving a good linux experience I didn't buy games for more than 15 years, so is not like the game developers were going to get 100% of the money I'm paying for games now, the choice is to get 70% or nothing because I wouldn't play their games. Not only that, if the proton compatibility layer fails, I'm very confident that steam's refund policy has my back, again, without this policy I wouldn't buy games.
Remember, not everyone is you, and not everyone plays games the way you do.
When you see in movies that the bad guy is bold AF and kills indiscriminately yet no-one seems to be doing nothing you think: meh, that is so unrealistic
yet here we are...
we just need a real life Liam Neeson that would kill all the bosses of Boeing, given that law is useless against the rich and powerful.
