Proton is certainly “cleaner” to use with Steam, but you don’t have to use Steam to use proton. I’d recommend adding the executable to Steam as a non-Steam game for simplicity. Otherwise you can use Lutris or find a tutorial online to run that specific executable with proton outside of Steam
If Lemmy were a centralized platform, then sure. It is not, therefore no single instance can be reasonably accused of censorship. If you feel censored by your instance, then you’re free to make as many new accounts on other instances as you want and avoid the offending instance.
This isn’t censorship, this is a community of people deciding they don’t want to hear the same bullshit they hear everywhere else on the internet in their own home.
