That would be great. I recently texted Proton, if they want to create a Nostr user handle. When nostr:npub1e3gvujkp43mxla5094jp74glse5e4daspammvpnr7thj3agzk48s09frly is really a company handle, this was might successful. But did not find any kind of confirmation on their official webpage. So I assume it is fraud until Proton can deliver proof of it not being fraud.
