Jack Ma vanished for merely speaking out against the Chinese party.

Jensen enabled China to build out the AI infrastructure it needed to get their models just shy of the SOTA models.

I'm not even pro USA (as I'm not American and we've been fucked over by then enough times), but equating literally enabling a foreign country in subverting your own is a large difference to Jack Ma whoes only crime was saying the Chinese party is destroying Chinas future with it's corruption and needs to be removed... (And he didn't even say that much, his statement was was tamer I just cba looking it up and am speaking from memory)
