I am sure it has gigameg blocks

This sounds an awful lot like bullshit. And in the end, it definitely doesn't sound decentralized. Decentralized implies independent relays operated by a multitude of independent operators. Like Nostr. If you need $30+ million to execute this plan, I don't see any way it's going to lead to the sort of independent architecture their nicely printed info card suggests. I'm not buying it.
