Microsoft enabled harder to ignore auto updates because users didn't want to update. If a user doesn't want to update, they shouldn't have to, as it's their computer. It's not their OS being used to harm users, it's users making their own decisions and accepting the associated consequences. Google should not be trying to force people to obey web standards, they should try to let users make their own decisions.

And then they plug that computer into a global multi-user network and their machine is botnetted and used to harm other users. In that context, people are no longer making simple decisions and accepting the consequences; a tragedy of the commons is instead created.
Your thinking works when computers are isolated from each other. When they're not, it's in the same category as "states require annual vehicle inspections." Because when you're sharing the road with other drivers, you owe it to them that your vehicle is unlikely to undergo catastrophic rapid disassembly.
