You don't get to have your cake and eat it by making the (supposedly) world ending model but also getting on a moral high horse.
It's the hypocrisy and obvious mendacity that's obnoxious to me.

You can release the powerful model to companies that will use it to fix instead of break.
If you really think a technology could be dangerous then the only morally correct thing to do is not help to create it.
They're not doing that, so either they're lying about it being dangerous, or they're lying about the fact they care (maybe a bit of both)
Nuclear can be used for great ill or great good. Today, most actual use is for great good.
By your logic we should have stopped at the discovery of fire.
