I think the main reason is that these services are targeting the entire internet of customers vs nostr, which has the more difficult price of entry, using public/private keys and bitcoin for payments. There is also too much of a focus in nostr on "what is possible" vs "what problems do people need solving". This is actually fine IMO, for now we're frontier tech, we need to experiment and try wacky stuff without too much of a focus on business dev.

Also, @levelsio is a special case. He's been at it a LONG time and has an incredible distribution network (his following) built up for all his products. Not many indie builders come close to his success.
