Yeah, but for a piece of software to acquire Linux support, you don’t need the majority of its developers to own a Linux workstation and want to use the software with it; you just need a non-negligible amount (i.e. enough developers with the spare man-hours to get the work done.)
Sometimes, in fact, it only takes one or two developers. I can’t think of a good Linux example here, but I know of a good few projects (Dolphin, for example) where the macOS target is supported entirely by the one or two developers on the team who use macOS.
Quite true, my comment was more against the typical HN remark that "developers" only use GNU/Linux, as if the software for the two biggest desktop environments would appear out of thin air.
