Yes, that's exactly why I avoid OpenAI and Anthropic products.
Besides the (quite true) joke, if sending data to DeepSeek is a concern the good thing is that the models are open weight, you can self host them or use third party providers.
You can theoretically self-host. DeepSeek is big. DS4 (the 2-bit quantization of DeepSeek Flash) runs on my Strix Halo with 128GB, but it's slow as hell. Completely unusable for interactive work. But, I guess a company that cared about data privacy and wanted a Good Enough local model could spend $100,000 or more on hardware to run it properly.
