That only strengthens the parent point. Switch to an OS where this requirement doesn't come into play if you're worried about any governments having a backdoor into your own machine.
I use BitLocker on my Windows box without uploading the keys. I don't even have it connected to a Microsoft account. This isn't a requirement.
Well at least you got that part correct. Do you just not know about security researchers? Or even bug bounty programs?
Why are you even on this forum? Doesn't seem like you know much about technology
Probably not now but not something unimaginable in some future.
However, since Windows can still run on user-controlled hardware (non-secure boot or VMs), I guess this kind of behavior could be checked for by intercepting communications before TLS encryption.
