You can use kodi on any old computer or a kodi device like Vero that uses OSMC. There are non official apps for most services. Some take a little time setting up, others just username and password. While kodi its self might not spy. The streaming services certainly still track what you watch.
I went for an old small PC so that I can get 4K on Netflix with Edge (most Android box tops at 1080p or less, I don't remember, because they are not certified by Netflix).
I can watch YouTube videos on piped.com, use a VPN to watch contents available only in other countries and in this way no one is spying on me.
