Going from memory, but in an old Bioware game called jade empire, you became a very competent warrior. At some point in the game, you learn that your old master manipulated you to fight his enemies and that he is quite the villain himself. As you fight him, your learn that he deliberately crippled your technique in subtle ways so as to have an advantage over you - should he ever need it.
I think the difference is - Chinese labs overwhelmingly submit papers, discuss techniques, ship open weights models.
If they decided to cut anyone off, it becomes gradual, as their tech moves on.
If a certain orange monkey decides his “super” intelligence is a negotiation leverage, the switch can be flipped and its dependents left high and dry.
If you fail to see the difference that’s on you.
