I mean, it's also the fact that they were the first to create a hub for the most massive secular technology trend since the advent of the internet.

This seems like survivorship bias. Kaggle was pretty well-positioned to do what Hugging Face is doing (and in fact, they are trying now somewhat). There's also a lot of others that tried to build a marketplace for AI models and failed.
Kaggle always was a place to conpete in data science contests to me. I never associated it with anything else. If they did sell ML models they did a horrible job letting people know about it
