Why do you think Jack Dorsey is involved? He left the board and didn’t take equity. He also did grants to Nostr and some fediverse stuff too but didn’t make it an investment. Wouldn’t you want billionaires donating money for open source open protocols without trying to own it? 

 Didn’t know he donated to the Fediverse?!

Anyone/thing in particular? 

 Ditto & soapbox are ActivityPub servers. He funded that work via an OpenSats grant.  

 Nice.
