That doesn’t surprise me.
Linux users are biased towards higher technical expertise, and they have a different mindset - most of the software that we use is the result of collaborative projects, and we’re often encouraged to help the devs out. And while the collaborative situation might not be true for game development, the mindset leaks out.
Another important detail is that Digg v4 pissed off most of the userbase, so the impact was pretty much immediate. Reddit APIcalypse pissed off only power users instead; the impact will only come off later (sadly likely past IPO).
