Yeah, that last one was a bit of a gutpunch for me.
See, I was a pretty avid Neverwinter Nights player, once upon a time. This was because, as a Linux gamer, it was the best really good isometric ARPG available at the time, ported to Linux. For a number of reasons, Atari bungled the porting arrangement with Bioware (for example, the cutscenes were all Bink compressed, and with no Linux playback engine, Linux players had no cutscenes).
Enter Obsidian, with a new engine, no Linux porting capability, and insufficient internal porting expertise. So, NWN2 had no Linux client. It's immature and unfair, but it felt like Obisidian killed off portability. So they took some blame.
Now, they start the KS with no Mac/Linux support, post an FAQ question stating that they're being looked into, and finally add the ridiculous $2.2M stretch goal for Linux. Seriously?
This is, of course, ignoring the fact that said funds could, instead, bring 35 QFI-style, truly indie projects instead
