The people putting their trust in the SR server side encryption obviously don't understand the difference between types of encryption. There is absolutely no way that the SR server side encryption is adequate to protect from 99% of attacks. Chances are extremely high that it consists of having things stored on a mounted symmetrically encrypted partition or container. That means that everything is in an unencrypted state while it is in RAM, which will be almost 100% of the time. If hackers pwn the servers, they can get all of the plaintexts. If the server is seized, unless the feds tremendously fuck up how they go about it, they will be able to get the plaintexts.
