I'm not exactly sure what studios to do in this situation -- WINE looks like cheating. It's not like there's some secret council that's like "mruhahaha Fortinte will be the destruction of gaming on Linux" -- it's that having stronger cheating protections is worth more than the losing the revenue of Linux gamers.
The number of Linux gamers who can't/won't boot into Windows for a game is a tiny portion of an already tiny market.
Don't call your mailing list "/dev/null" then, because it does not sound very appropriate given the recent policies Riot has chosen to apply? To me, it makes zero sense to showcase a Windows-specific product by writing a blog post starting "/dev/null", right after openly saying Linux/macOS/BSD users can go screw themselves.. It just feels like an improper appropriation of sort.
