My NewPipe app stopped working for a week and it wasn't difficult at all living without YouTube. There's tons of content in the world that can be consumed in its place.
I use NewPipe only despite having a current YouTube Premium subscription because the official app is bonkers. It's hilariously stuffed with useless features that can't be toggled off(games, shorts), half baked stuff like specific video quality can't be chosen for all videos by default( has to be on a per video basis). Oh, and every other time I visit some channel, asking me to join the YouTube's channel for additional perks. You just took money from the user to give them a sub par experience.
