What evidence? You didn't link any. Searching for the hints in your comments brings up marketing by Anthropic "data you sent to one company is being sent to another without your knowledge or consent!" Anthropic also states this without any evidence, but I'm not suggesting it's not true!
I am so glad we never see stories against Anthropic/OpenAI claiming that! Thankfully we don't even have to search, critical thinking is enough to know that Anthropic/OpenAI are responsible data sovereign and others are not.
Nothing short of unredacted network logs and packet dumps would convince people like you (and even then you could just say they are forged). In the eyes of HN the Chinese model providers can do no wrong.
Anyways, they can easily be sued by DeepSeek if they are lying.

Critical thinking is not relying on a confirmed bad actor because you think the others maybe could be bad actors.
