I am very happy with Jellyfin, although I only have a very basic setup (also to stream to a smart TV). It just works so far (after figuring out the permission to read my files on linux).
Edit: Emby annoyed me a little since some features are paywalled.
I wonder when google is going to tap into Gmail data of users (if they do not already). They must have trillions of english messages and they already filtered spam. Additionally, it’s hard to ever prove that they did it.
Maybe it doesn’t make for high quality data though, not sure…
