(Of course, I'm talking about Matasano Security / NCC Group ;P. I knew people there when you all worked out of the Dental Fabulous--no clue if you still do--and had some incredibly awkward run-ins involving Apple people, as everyone on all sides wanted to pretend that no one knew anyone else, due to what I'm sure was a ton of NDAs, explicit and implied... it was pretty epic, actually, as one of the people involved was essentially a "double-agent"! Regardless, I'm willing to believe that you had just left before all of these contracts with Apple had happened, and it certainly undermines the premise that you yourself don't need one of these devices to do research, so "point still taken".)
I left Matasano more than 6 years ago. Unfortunately, Matasano SFBA moved from the dentist's office (which I have fond memories of) to Sunnyvale. What I'll say right now is: I have the same disclosable interest in Apple's security as most veterans in software security: they're an elite employer and I have a bunch of friends there.
(The more important disclosure is that I don't specialize in the kind of work that would likely benefit from an unlocked phone.)
(2) I'm a software developer at Fly.io.
(3) Latacora, my previous security company, did no work at all for Apple.
(4) I have no idea what you mean by "server security"; you are probably thinking of someone else.
(5) I'm not asking whether you think it's OK that Apple sued Corellium. Most people in software security are not happy that Apple sued Corellium; I'm not going to be the oddball pissing into the wind this time with a contrary take.
If we agree, we agree, and it sounds like we do: one might not believe that the SRDP meaningfully improves security research on the iPhone, but it's hard to make an argument that the SRDP _harms_ it.
