Very true and it is my favorite part about DVMs, honestly.
Google sign-ins, emails and passwords are a nuisance nowadays. Beyond a nuisance, a liability. Hacks, data leaks and de-platforming are a very real possibility with any new service sign-up.
The network effects of nostr and DVMs are not yet realized. While there are only like 3 DVMs that reliably do image generation, there will be more to come. Whereas to test new APIs, each service is a new sign-up, another credit card link, and new programming documentation to learn.
Still optimistic!
