It's reasonably likely that a lot of people linked to the federal government want to ban DeepSeek. You can tell it's being presented away from "they gave us a free set of weights" and towards "they destroyed $1T of shareholder value." (By revealing that Microsoft et al. paid way too much to OpenAI et al. for technology that was actually easy to reinvent.)
It took them years and years to move forward with the ban ok Tiktok and it still hasn't been banned yet. There is no way they are going to ban some MIT-licensed weights.
>"they destroyed $1T of shareholder value."
The market has largely recovered.
