Honestly, the 2 hour refund window is the perfect length to see how bad the Linux compatibility is. A half hour to try a few tweaks, if I care enough to. Another hour to see if there are subtle bugs or intermittant crashes.
I definitely have tried to run a few games I wouldn't have bothered with otherwise.
And to speak to grad and hexbear, a large part of the reason there are commies here is because they were driven off other platforms. Hexbear and Grad are both decendent from active communities that reddit banned.
Seeing all the scaremongering about those communities here reminds me of the old comic. :
