Exactly. Making the game WINE-compatible is not the same thing as committing to support. In reality, the only thing stopping WINE from working is Epic Anti-Cheat and the absurd thing about this is that Epic already gave EAC a WINE-compatibility mode -- they're just actively choosing not to turn it on.

What Tim's really saying is this:

I don't want our flagship game to be used as a way to highlight Steam's better Linux support, so the game won't come to Linux until EGS on Linux is at parity. Unfortunately, it doesn't make sense for us to bother doing that right now because the Linux usershare is too small to matter.
