We are talking about health because I started this thread with a discussion about the healthiness of the situation. Bringing up jailbreaking is an extremely strong argument because many of the same people are involved, rather than whatever vague "competition the real world" example you have shows. And I know that the currently situation has already turned off some very capable people from contributing to either "side" when they were perfectly willing to do so before, or waste their time on arguing who is in the right here.
But of course many people who are working on this are driven by the competition as well. Both collaboration and competition have their place, but make no doubt, the world itself is proof that competition is likely the primary driver behind why Linux was up and running on the M1 so quickly.
