I'm self-hosting Piped and couldn't be happier. Clean, distraction free and, importantly, private. No data mining. Importing your subscriptions from a Google Takeout dump is simple.
LibreTube for Android is my mobile client, and talks to my Piped server without any issues. The only thing missing at this stage is a client for my Chromecast GTVs. For those, I still watch YouTube with SmartTubeNext, which means keeping two sets of subscriptions in sync. A little frustrating, but relatively painless, for the privacy benefits.
Yeah, and this is where the part of my comment that discussed "laws that apply" is nuanced. If the laws that apply are designed to abridge people's autonomy, and right to privacy,, then that's an unjust law.
