It's an open secret that Windows is backdoored for the NSA to be fair and that isn't even including the truly dodgy stuff like Intel Management Engine being a backdoor on a BIOS level with remote access
Do you have a source for literally any of those allegations?
I'm as big of a Windows and ME hater as they come, but I'm not aware of any proven backdoors in either. Especially ME, which has been thoroughly reverse-engineered by the security community by this point. The only 'backdoor' discovered was the undocumented killswitch command that disables it after initialization.
It's safe to assume that Windows is backdoored, as it's closed, not audiatable and is a part of PRISM. It's not a proof, but this is how good opsec works.
And yes, this is not equivalent to what the parent said, but your reaction should be similar.
