After checking their github repos I’m only seeing a web mail client with metamask for auth instead of user password. It’s using a normal graphql api. Very decentral. I guess web3.0 only requires a „login with metamask“-button now.

Oh, and about the cool, very decentral drive on IPFS thing: the drive is still only on a single server, pinned by a single server. That’s how IPFS works. It it would work otherwise and they didn’t have to actually pay their storage bills, they wouldn’t limit the storage to a mediocre 10GB less-than-gdrive shit tier.
