I know some people praise the lack of an algorithm because it makes them spend less time on YouTube but I don’t have that problem anyway. Almost all videos I’ve watched on YouTube. I found through the homepage. The lack of it makes the alternatives useless for me. I’d even maybe be fine with something that takes all the watch next recommendations of the videos in the subscriptions page and jumbles them together as “recommendations”.
To provide “personal recommendation”, an App would most likely need to profile you, i.e. track your viewing habits and trends, and forecast your areas of interests.
IMO this goes directly against the concept of privacy.
On the brighter side, I think Freetube (local, on windows) and LibreTube (on Android, but needs a piped account) can provide personalized video suggestions, but you yourself should check them out.
Precisely, principle unsound, do your own damn research.
I disagree, a properly implemented system could be pseudonymous. You may not consider that perfect, but it’s not of no value.
