Yes, Microsoft would probably not divulge such user data freely, and
perhaps not even under subpoena. But consider Microsoft's risk model in
gathering the data. Conspiracy theories aside, they arguably gather it
for debugging and marketing. So even if it's encrypted, it may not be
secure against resourceful adversaries.
So anyway, if I wanted to use Tor on Windows machines where I couldn't
install stuff or boot Tails, such as at school or work, or in public
libraries, Tor browser would be my only option. I do get that. And for
sure, I would want a hardened browser.
But still, I would feel betrayed if Windows leaks pwned me, and Tor
Project hadn't warned me about that. And further, if I actually could
have installed VirtualBox and Whonix, I would feel betrayed that Tor
Project hadn't recommended that approach.

Right. And it's not just that Windows leaks data. It's just such a
security nightmare. Consider the FBI's NITs. Even if they have a Linux
dropper and payload, it would fail totally in Whonix, unless it could
break out to the host machine.
