That doesn't mean I blindly trust them, only that despite seeing potential for abuse I judge that they have more incentive to be telling the truth than not.
Also check the comment by user faitswulff where they mention how they have been subpoenaed "and could only supply account creation time and last connection time".
>> There's no technical solution in any technology for preventing the other side being compromised, as far as I can see.
I don't know Matrix, but I can guarantee that it doesn't solve the problem of a compromised client obtaining the messages willingly sent to it.
If the NSA did have it backdoored somehow through the OS, it's a good bet they'd force LE agencies to use parallel construction to keep that information top secret.
That is why we really need open source hardware and OS's. A good (or even functional) open linux phone can't come fast enough.
Your solution?
* Magical amulets?
* Fake your own death, move into a submarine?
* YOU’RE STILL GONNA BE MOSSAD’ED UPON
- read the source code and are satisfied that it's secure
- compiled that version of the code
- installed it on your mobile or desktop
You're still only as secure as the client on the other side of the conversation.
If that one is compromised (has not gone throught the steps above) it could very well be sending all messages in clear text to a malicious party.
