Me personally because I don't have a Google account nor saw a real gain in getting one (for what I do in my day to day), I just switched to these for subscriptions.
+to that.
However I haven't found proper alternative yet.
I got so used that dump algorithm that at least 40% of times recommends what I'm actually interested at, that it feels so hard to go back to watch unordered vids
Newer content is still lacking on alternatives. Like coding tutorials or documentaries etc.
On the other hand I found many old forgotten internet classics on these alternative sites like old ads and funny clips that we used to watch at 240p back in the day.
Point one hits home. It's nice that I can look through my feed but I also want to find new stuff and piped is not giving me that. I still use it in case my yt account gets banned lol
