Proton and Mullvad have the best privacy record, but I want to suggest a different tool. VPNs are really only useful for tunneling and adding an extra layer of anonymity, there's no total assurance they won't rat on you or get breached.
Real-Debrid is a way to torrent without risking ISP shutting down. Other debrid services exist, I just prefer real-debrid. The debrid service does the illegal part and you download over high speed. It's also more available since you can think of it like a very large scale seedbox. There's also implementation for most media center apps.
If you have a problem with Tiktok but don't have a problem with Facebook or Instagram then your opinion is worthless. At least tiktok makes a good product, so good that American lawmakers are scared because they can't control them.
