Last year, I pointed out how many big publishers came crawlin' back to Steam after trying their own things: EA, Activision, Microsoft. This year, for the first time ever, two Blizzard games released on Steam: Overwatch and Diablo 4.
I understand that it's normal, but the argument still doesn't make sense for the purposes of this discussion. For people who do use Linux, it is worthless since they can't use it. I also can't blame Linux users for not liking a company that has been hostile to them (i.e. removing Linux support from a game that had it.) You're just reinforcing that Steam is a better option for them.
