I didn't mention OSX because I didn't want to be overly verbose but yeah any non-free OS at this point has pretty much no respect at all for privacy or user freedom.
Wait, what is Apple doing? Which Apple OS is sending a hash of every file that is opened? And can this be disabled?
The intent seems to be malware prevention, but yes, the implementation is terrible from a privacy perspective. Far better would be a local bloom filter or similar.
But the bit about Windows being more respectful of privacy is not correct, or at least substantially more complicated. For instance, if you run 'full' telemetry, Microsoft can, in fact, pull your documents from your machine and execute things on it remotely, something I've seen no indication Apple does.
