I agree that they aren't exactly good citizens in the corporate sense, I'm all for regulation to step in if companies won't voluntarily do it. To your point Google does unlock their bootloaders so they seem OK with it for their devices?

There is some planned obsolescence in incremental improvement of technology but that that is probably too slow for them (e.g. my S10/S11 lacked LTE, 5g, eSim...).
