Yeah I agree. To be clear, if you take the reverse of my statement, i.e. if you're on Windows, you shouldn't use Tor, then I would be gatekeeping.
But I'm not implying that, but rather the reverse. I'm saying if you have use Tor for whatever reasons to bypass censorship, do illegal stuff and avoid being tracked, you should at least be aware that at the kernel level, how you're accessing the internet has already been compromised by Microsoft, and consider alternatives OSes
Of course I'd still want people running Windows to be able to use Tor, and also I'd say leaving Windows isn't something you would only do at the "highest threat model".
Privacy will almost always be a trade-off with convenience, I'm pushing the awareness to get people to act, should they choose to. That's all.
