That is meaningless to me if the app can't do what I need it to do. I don't need every feature of the YouTube app, but there is some key functionality that I need.
I see this snooty clap back every time someone dares give any criticism of youtube alternatives. "Lacking Google" is not a feature, nor does it make up for lacking features most users would call fundamentally necessary.
For some people it is a feature. For you its not. You're one data point. You appear to have the same attitude as the people who leave drive-by feature demands on open source projects, then get hostile when they're ignored. The app isn't for you, and you're not entitled to features in a free, open source project. Its not a "snooty clap back", they're actually correct. This project isn't for you, and writing a manifesto of features they need to implement to add one user is pretty absurd.
Imagine downloading a free textbook and emailing the creator demanding additional content or else you'd stop using their free textbook? This sort of thing just reeks of entitlement and a misunderstanding of open source more than anything else.
Lacking Google is the raison d'être of all of these apps and most of that list there is useless crap I am never going to use. The only things I would need out of that is saving my place in videos and picture in picture (maybe).
Plus half that is list is just copy cat implementations of other more well used sites.
Who is going to youtube for copies of tiktoks and twitch streaming?
I seems that you want all the features the official YouTube app has. Why not use it?
If you don't want to see ads, pay for YouTube Premium if it's available in your region. Otherwise you can certainly create a fork and add those features and nobody will be angry with you.
