No, paying Nebula as an alternative to paying Youtube doesn't work for many viewers because most creators who create good content are not on Nebula. E.g. Many popular channels with worthwhile info such as Applied Science, Technology Connections, 3Blue1Brown, etc are not on Nebula.
Also, many people who use Youtube for learning DIY repair, hobbies, coding, etc and Nebula doesn't really cater to those genres. E.g. I watched some videos about configuring Unifi networks and then some tutorials on installing some flooring. These types of videos are not on Nebula's platform.
There is a huge variety and scope of educational material on Youtube and platforms like Nebula/CuriosityStream only have a fraction of that.
Nebulas Android app is insultingly poor quality and pretty much unusable on tablets/foldables (it locks in portrait - who the heck still does that on a VIDEO app?!)
I've had college students build better apps for homework. It's insulting considering the rather high price of a service.
