I followed your link, then struggled to find something as you have to choose from a list of thumbnails. I then clicked to view something and immediately hit a paywall.
How are you supposed to "discover" this content? That is where youtube is so strong. Often on youtube I will be directed to patreon, etc - does this work on the same principle?
A lot of large YouTubers (like Wendover Productions/Half as Interesting) have been doing sponsored ads for a thing called 'CuriosityStream' which is basically Netflix for Documentaries/Non-Fiction and as part of a bundle if you subscribe with their link you get Nebula for free as an extra for as long as you pay for CS.
It's mainly existing content from YouTubers but with premium exclusive videos like Patreon has.
