Is Session actually secure though? I know they're based in Australia, and as an Aussie myself, holy fuck would I not trust this country for even a fraction of a picosecond with anything private or sensitive. We have some of the world's most draconian and far-reaching digital privacy and surveillance laws, and I'm not ready to accept that Session hasn't been secretly compromised by the AFP, given the law against revealing government backdoors.
Happy to be proven wrong, but I always err on the side of extreme caution when it comes to Australia. Digitally, we're closer to the CCP than any of our fellow western nations.
