1. The Tchap issue was specific to the French deployment, rather than being a bug in Synapse or anything Matrix specific. (It was actually a bug in python, fwiw: https://bugs.python.org/issue34155. Agreed that it should have been caught internally though)
2. Yup, unfortunately matrix.org got pwned 4 years ago. (Thankfully E2EE means that encrypted conversations weren't compromised). This was a (bad) sysadmin fail; again, nothing to do with Matrix, the protocol, or the implementations (and the rest of the network was of course unaffected).
3. I've never seen any evidence of Amdocs being involved in spying, and many of the accusations there seem to be rooted in antisemitism. They acquired the two companies (one UK, one French) which turned into Matrix in 2010; we span out and set up Element in 2017.
