I don't think Microsoft's interest in Rust boils down to preventing jailbreaking. It'd be far, far cheaper to lobby the US government to ban it.
(Jailbreaking has always been an arms race, and memory corruption exploits may eventually reach their natural end. But that'll probably be because of things like PAC, not Rust. When that happens, I expect jailbreakers to move onto the next low hanging fruit.)
