And then you'll end up with letting them take away features, introduce new bugs and other bloatware you never had before (seems to happen semiregularly with GPU drivers...), can't use hardware you bought because they broke its driver at some point, etc.

No, personal responsibility and community trust is infinitely preferable to corporate authoritarianism.

The problem with that approach is that malware can bring its own signed driver to load and exploit.

Microsoft would need to blacklist the known vulnerable drivers to solve this problem, but then devices will stop working.

No, just use SDI Tool Origin if you have to suffer Windows.
