bull shit. they retain everyones data indefinitely anyway regardless of whether the person is using encryption. so they use your data as an input in their research to learn how to break the encryption? big deal if you dont encrypt they just read it with out even having to attempt to break anything.

this sounds like a really bad bluff to me. they know they wont be able to break encryption for some time so they are trying to scare people into not using it.

This argument is synonymous to the argument that if everyone leaves their front door open, a burglar is less likely to choose your house. I agree with pythonista that we must have wide adoption of crypto.

Cryptography may not guarantee privacy but it protects work/messages from entities that can make allegations that aren't true.
