Has there been any disruption of profits and influence of western corps due to RISC-V? To my knowledge, not yet and its not a sure thing.

Not yet, but something like Deepseek did disrupt some profits. If RISC-V keeps developing and lowering in costs it my may do the same, but as of now it's still pretty pricey and experimental in use.

Im not entirely sure your point of view is a win for OS. When other nation states view it as a threat instead of an option it leaves the door open for all the sabotage, etc. that nation states to to each other.

I'm just talking about the hardware here. Hardware is much more agnostic, and the costs going down + it being open means other countries can eventually manufacture their own at a lower start up cost and increased profits compared to say ARM.
