Fediverse doesn't actually solve a problem I have. I'm not on xitter or instabook or myspace and don't want to be. The one saas i really need is email, which is 1. Already decentralized and 2. Getting harder to self host every year due to the escalating war between slopspammers and security measures.

Signal solves the async messaging and phone surveillance satisfactorily for my "threat model".
