I don't think that's how the market works. Anti-slavery regulation didn't stop slavery either, just moved it abroad. Same for trash handling regulations, it's just shipped abroad. Falling behind on useful AI capability is obviously not in the interest of anyone, so either all players coordinate, or an arms race towards ??? it is.
It may very well be self serving what they're saying, but that doesn't mean it isn't simultaneously true.

Hence the argument that they're either full of shit, or psychopaths who need to be stopped at all costs.

I think you're sort of right, but then I'd have found it very strange / deeply suspicious, if during the time of slavery being legal, advocates of abolitionism were practicing slave-owners.
If you think AI is going to destroy humanity, it still feels absolutely crazy to leap to "well I might as well be the one to profit from destroying humanity".
