Or they could just do it themselves. They think that they personally could end the world, apparently. Nothing prevents them from just deciding to do this, entirely on their own.

No, how about they don't get to use the government to enforce their duopoly. Just slow down, on your own. They are the frontier. They are massively ahead. Its not that big of a deal if a few others catch up a little bit.
I mean, they think it will end the world right? Maybe just take the small hit and following through. There is even a perfectly rational business reason for them to slow down a bit, because of all this bad PR they are getting for going so quickly.
They are not forced by the gods of capitalism to be as reckless as they claim they are being, and we do not have to bribe them with enforcing their massive lead. They can just slow down a bit. On their own. They don't get to try and blackmail the world into giving them a government enforced monopoly exemption or handout.
