> Windows will happily run unsigned binaries

This is absolutely false, it's a simple policy change to enforce code signing, any organization that is serious about security can do it.

I'll give you the benefit of the doubt and assume you're another Linux guy who doesn't understand Windows security.

The concern of course is with malware being signed, which is far more likely to be abused than some TLS MITM fantasy.

You already need compromised systems to install malware, signed or not. Not a real problem.

For TLS MitM you just need to use a shared network, wired or wireless.

Plenty of major programs are not signed, and thus plenty of organizations don't enforce code signing.
