Popping into a Linux community to stick your tongue out and letting folks know you are going back to Windows? That's no better than a troll.
This post is opening up a discussion on game compatibility on Linux. Switching back to Windows is just one point OP made, which you decided to focus on.
If you decide to view this as a troll, you should also condone the people who invade Windows-related Lemmy posts just to advocate for Linux.
Are you dumb because the device you're on uses proprietary firmware?
