But there's no distinction between a security patch and a feature update. And it's never just an update to only get new features. It's to get bug fixes and better compatibility with new programs (I'm thinking of libraries and dependencies). And there's the case of Windows and Chrome OS, where software updates cannot be opted out of by official means.

When I think of planned obsolescence and sorta-unintentional performance regressions on desktop operating systems, I'm instantly brought to YouTube's Polymer website and UWP. Two complicated things but they largely only benefit the developers of the software and have not actually delivered any features. Google is a huge part of the desktop world and they're not so "external" as pabs3 says and to me it's just part of the software right to repair movement.
