"Windows 10 would clearly be considered spyware 10 or even 5 years ago. Yet somehow Microsoft has convinced the general public that it isn't, and we are supposed to still trust them?"
No. Microsoft decided to go into the data business with Win10. They very publicly partnered with the federal government to feed them info from any Win10 system that 'might' have something illegal on it. Go back and find their statements prior to release, they are downright dystopian. So yes, Microsoft has publicly said if they detect a music track that may have been downloaded 'illegally', they will 'package it and all your info and send it to the feds'. It isn't spyware if you partner with the spies.
