It's a service that will offer LN, ecash and custody of your bitcoin in a shared thrust. To me I will probably use it for lightning bc its a good trade off, harder to rug pull than WoS will also get a lnaddress probably and don't need to run a node on my phone, and free txs with echash for users in the same Fedi. Many people will also use it not to self custody and not leaving on exchanges, but I don't think those will be too many though.
