OS upgrades vs security updates is a whole different ballgame. We should not confuse the two.
Windows forces major upgrades in many cases, sometimes rendering the device inoperable because OS upgrades carry inherent risks. Forced upgrades are simply irresponsible. We need that consent to let the user back up files beforehand as a bare minimum, even overlooking the ethics side of user consent. Is MS going to fix my parents PC when they break it?
Forced updates? I see the argument, but I have to insist on user consent at all times. By default is okay. Explicitly violating the human’s will seems wrong. Software should serve people. But I can understand the argument even if I don’t agree with forced updates.
