The issue is not open weights as a whole, indeed Hegseth himself said they are important for America (if American made, presumably); the issue is Chinese models, whether open or not, and that's what's looking to be banned, and nothing in this article suggests otherwise.
The conversation going on in the industry is a bit broader than that. OpenAI's head of strategic futures just said last week that open models are inherently decelerationist, ungovernable, and will slow development on the frontier. You'll notice OpenAI does not appear as a signatory here despite their relationship with Microsoft.

Is the US planning to invade China and take away their models? Because otherwise China is still going to have the models even if the US bans them. I don't think they're going to be going with the US position on this one.
Why anyone would care what Hegseth thinks about open weight models? What's wrong with Chinese models? The censorship? I think it's good to have diversity of opinion. Get US flavored output on sensitive subjects from US models and ZH on ZH models. That's a useful tool.
What is a "Chinese model"?
If I change one weight in Kimi, is it still a Chinese model?
If I fine-tune Kimi on pro-America nationalistic freedom loving anti-Chinese propaganda, is it still a Chinese model?
If I distill Kimi from one server to the next without ever directly transferring any weights, is it still a Chinese model?
If Claude accidentally trains on some of Kimi's output, is Claude then considered to be a Chinese model?
If China's next open-weight model is released secretly through a European company, is it still a Chinese model?
