How much bureacracy does it take to publish extension? I see the guy has his address there and tax entity.
Probably not much. nostr:npub1zfss807aer0j26mwp2la0ume0jqde3823rmu97ra6sgyyg956e0s6xw445 would know
This is my experience when publish Nostr Connect
- Firefox: free, you only need to register a mozilla account
- Chrome: you need to pay $5, but you can register random gmail for publish extension purpose
- Safari: you need to pay $99 for developer account, and a macbook with xcode installed
