I originally switched out of privacy concerns, not that MS or someone else was stealing my personal data and work directly but that it would just inadvertently get leaked with some massive cloud fuckup as seems to happen regularly.
Since then I prefer it just because I can run it on decades old hardware, it’s consistent between different versions of the same Distro (W7 through to W11 gives me anxiety), and I don’t have to worry about a hardware change invalidating a product key so I have to re-buy my damned OS. Shit, yeah, it’s an ideological thing.
