That's also my choice. If I don't service my car every year then no-one comes to take it away from me and do the servicing anyway. And sure, the average person won't make sensible decisions for their own good about updates, so forcing them can be a reasonable default, but it should still be possible to override those settings. It's my computer. As for choosing when to do it, maybe that's possible (although it's not been my experience tbh) but that all falls apart when, for example, an aged relative switches on their computer once a month to do one specific simple task and ends up having to wait two hours while their bargain basement machine grinds to a halt force-updating itself because it's past the update grace period.
