Anecdote: some one else's account of this was that it was really helpful because the Linux portion of the community (while much smaller than other segments) provided consistently high quality feedback/bug reports.
That was just one company though. Other devs have said it isn't worth supporting Linux because the majority of the bug reports they get are distro specific edge cases.
That anecdote is in part due to the fact that the engine that was used was already Linux-friendly and was already ironed-out, so it made sense that more agnostic bugs are reported, whereas other developers resent (native) Linux support due to distros not even fully following LSB or outdated libraries, which in Windows has at least the concept of side-by-side libraries.
