And every bit of our tech that hits the market is going to be seriously shaking up the status quo. I mean, we've already turned the energy sector on its head, and the moment our new Legionary suits and MAKOs see actual military action the entire non-Alliance galaxy is going to be browning their pants, and probably sending waves of black ops teams after us. ..."
As long as we continue to sell our tech to other interested buyers, even with a small time delay, I don´t think we would have to fear assassination via STG etc. The only true galactic power that will probably try something are the Batarian since they left the Citadel and thus do not profit by its patent law/galactic market zone.
(historically the few confirmed death of weapon researchers I actually found where due to working with the arch-enemy(for example: Israel killing Iranian nuclear scientists) or because they wee perceived as betraying their previous employers.)
