I'm not sure the U.S. as a whole is stymying open source -- or at least there don't seem to be governmental pressures to keep things closed source. Take the llama models, for instance.
Can these events be considered US is stymying open source [1], [2]?

I guess this may prevent USA affiliated developers from collaborating with certain designated foreign developers.
It’s possible that the DeepSeek team or other top foreign developers may become sanctioned by OFAC. Then forking their models may be considered transacting. This would certainly be disastrous for US researchers, if the pace of progress out of foreign teams continues.
But then again I’m not sure why the powers that be would effect such an own-goal.
For marketing reasons alone Meta (US) and Mistral (French) should have launched and promoted standalone apps just like DeepSeek did for R1/V3. Many people think DeepSeek's models are the first that can be self-hosted because they simply haven't heard about LLaMA's or Mistral's models.
