Their AI sucks, this is what happens when a site curates their feed instead of just using hashtags+views+popular.
I've been using pockettube addon and just add my favorite channels to groups. Now I can just watch tech, and get my favorite tech shows. Cars, Music, etc. Plus I get uncensored and time/popular feeds sort views again for each of my groups. This is 10000% better than clicking "subscriptions".
Sad people are just herded like sheep on what content they consume.
