What's the big deal with Deepseek privacy matters?

I am seeing loads of fuss.

As a worker for a US company, I have been told to "you are not allowed to use Deepseek".

I thought all companies collect chat history to keep training models. Why does it matter so much now? is it just because this case is not benefitial for the US or are there bigger concerns? (like Deepseek being some sort of hazardous virus)

I obviously don't care. I will use it cuz I can and cuz it's free. I love being an ignorant consumer. Life is good!

Thanks China!
