Thanks for the links! It is very interesting, but I', not sure how/if what kind of influence this has on Matrix. Just because they were born out of a shady company, doesn't invalidate the project. Heck, we're using software (Disassemblers) that are maintained by the NSA (Ghidra) these days. Since they are open source (just like Matrix and Element) we can still be pretty sure that they're not doing anything shady.
