Combining dragnet surveillance with device hacking is intended in the design of both tools. Hence, State Department-funded Signal dupes you into handing over your identity as part of the population-centric mapping. In custody, your phone will be hacked when it is taken away if it’s important.

What data is there for Signal to turn over? Can you prove that they’re keeping messages or logs on their servers that have ‘disappeared’ from all the associated devices?
Your entire social network graphs, and timestamped message history.
No one can “prove” signal doesn’t store everything. If you give me ssh access to their server, then I can verify. Otherwise it’s “just trust me bro”.
