The head of the Signal app has criticized plans in the EU to allow messengers to have backdoors to enable automatic searches for criminal content. Signal is considered one of the most secure messengers.
That is how the signal protocol works, it’s end to end encrypted with the keys only known between the two ends.
The issue is that servers are needed to relay the connections (they only hold public keys) because your phone doesn’t have a static public IP that can reliably be communicated to. The servers are needed to communicate with people as they switch networks constantly throughout the day. And they can block traffic to the relay servers.
Signal does have a censorship circumvention feature in the advanced settings on iOS which may work when this hits provided you already have the app installed. Never had to use it though.

I think they’re suggesting doing it on top of SMS/MMS instead of a different transport protocol, like Signal does, which is IP based
Which is what Textsecure was. The precursor to Signal. Signal did it too, but removed it because it confused stupid people.
