Awful to self-host (resources, administration) and rolling their own crypto
On the UX-Side itโs too complicated to explain to my parents.
Iโd love for it to succeed, but for now Iโll just stick woth Signal

rolling their own crypto
No, it uses well-known, well-proven, standard crypto.
It also uses double-ratchet key management, much like what Signal does.
The reference server is a bit heavy if youโre federating with large public rooms, but lighter alternative servers are available.
