Yes it is. Although I personally have far less moral objections to it.

To elaborate:
OpenAI scraped data without permission, and then makes money from it.

Deepseek then used that data (even paid openai for it), trained a model on that data, and then releases that model for anyone to use.

While it’s still making use of “stolen data” (that’s a whole semantics discussion I won’t get into right now), I find it far more noble than the former.
