It does matter if you're selling someone on the idea of switching away from their mac or windows machine that they're complaining about something the OS vendor has done by highlighting that with Linux they could "fix it themselves". It misses the point that most people don't want to "fix it themselves" and even if they had the inclination to that, for many problems they don't have the time or the skills. If someone is upset that Apple forced a move to Liquid Glass with Tahoe and all the bad UX that comes along with it, it's possible that they could also have the skills to fix their OS if they were equally upset that their chosen linux distro switched to Wayland. But it's more likely than not that they don't have those skills and so for that user, Linux is theoretically an OS they can fix, and practically just as likely to force them to accept the march of technology as any other OS they use.
