Even with full e2ee, they still have
- Your real identity (via phone numbers)
- The real identities of everyone you talk to
- Who you messaged, and when
With this its easy to build social networking graphs, and tag everyone implicated with a targeted account as an accomplice. Reading and trying to build meaning from the e2ee message content is almost less important than social graphs.
There’s a lot of dead accounts downvoting you BTW.
