Mark Riedl: Why isn't HuggingFace suing OpenAI? Because being hacked by OpenAI is a huge PR win for HuggingFace, who is now using it to rally around the cause of openness. www.nytimes.com/2026/08/24/t...
The Data Therapist in the Blue Sky : Regardless of whether they should sue, I don’t follow this logic.
