You my friend are living in a bubble. Most users are using default apps. For your own safety do not go out of the bubble, it’s wild out there.

99.99% of users are on the official client, as is the case for nearly every major web platform.

I switched off from the official app back to Tubular, a NewPipe fork. I was always a NewPipe user but gave YouTube app the chance because I have a YouTube subscription( though, I mostly used it for YouTube Music). But even with a subscription, third party apps are much superior.

Their is no Sponserblock integration in official app. Plus Shorts and Games thrust on you. Oh, and did I mention whenever I go to certain channels, YouTube asks me if I wish to become a member of that channel for extra perks. Like, I just paid you money, Google, stop asking more.

I use browser for no ads. Applies to many others too. I avoid downloading apps as far as possible.
