what information is provided to an entity about whom.
“Content” and “Context”
Why is only message text considered “information / content / context” here. Signal has your real name and address via phone numbers, and has every other real person you talked to, and when. Why is “message text” considered context, but social networking graphs aren’t?
All these definitions are highly subjective, and the above one clearly considers social networking graphs to not be “content”. Basically they’ve re-defined privacy in a way that excludes highly sensitive information like everyone you talk to, and when.
Prove it, give me ssh access to their centralized server so I can verify that they’re running the code they’ve published. Otherwise this is a “just trust me” claim.
There are 10 websites that publicly publish phone number and identity info, right now. Not even a government, but a random stranger can convert your phone number to your real identity.
