Not the OP.

I'd say that we need regulation requiring user-replacable software. Even though a PC might not be supported by Windows 11, and subsequently major browsers will cease support. You can still install a 3rd-party OS like Linux which will maintain support far beyond the original EoL.

Same goes for Android devices, I used to have an LG G2 (the phone, not the TV), which IIRC shipped with Android 4 or 5, and through LineageOS I updated it all the way to Android 11. Granted it couldn't remain relevant forever, its 32-bit ARM architecture is quite outdated and a lot of apps lost support for it, but for a while it remained quite useful.
