Based on my own experience and reading, I do think there's a general consensus on this site but I could certainly be wrong about that. I'm less concerned about hypocrisy per se, it's more that the arguments that are used, even if by a minority, seem to apply in only circumstances in which China releases open-weight models.
I am aligned with your viewpoint as well. And I've repeatedly argued it. If China were to take the lead the US can then just release open-weight models. Folks say having the lead doesn't matter because China releases cheaper open-weight models. We can just let them take the lead and then do it back to them.
