"wow why don't people like it when software companies market their software as working on their computers, when in fact the software only incidentally works on their computers due to an unrelated project"
"haha look at all those audio APIs on Linux. they can't even decide on one way to do this simple thing" that's because it's not simple. general case routing of audio and MIDI is a really hard problem. people pay hundreds of dollars to solve it.
"wow Linux is so hard to develop for. there are so many distributions and so many sets of libraries." yeah you don't ship your games for Windows Server 2019 either. just pick a distro and ship. maybe ask around a bit.
FWIW, I generally don't resent gamedevs for cheaping out on the Linux port. Linux is on <2% of PCs and not really friendly to running shrinkwrapped binaries out of the box so from a cost-benefit PoV, I'm surprised *anyone* ports games to it at all.
