Yeah I came here to say something similar. This is ARM's game to lose, and they need to remember that their architecture was in the same situation as RISC-V is at some point. The only thing that stops RISC-V right now is that everyone is focused on ARM. If ARM gives their IP users a reason to switch by raising IP costs or making bad architecture decisions then RISC-V will take advantage of that to make inroads. History is full of incumbents that go on to lose their entire market when they get complacent.
