I'm not sure why Mark can't add the "join" feature to YouTube. Does anyone know?

Sarah what do you mean the “join” feature? Be more specific..you mean join the app? Join the discussion? Have no clue what you mean but I also don’t go into the forums normally. I’m Always on my mobile device that’s why

I am not sure, but my guess is that YouTube takes a large cut of the subscription cost. Also, I dont know if they allow certain videos to be on YouTube at all. This is an extreme example, but I dont think you can "join" and then hardcore porn is unlocked, but idk thats just my take on that.
