Sure, and when you invest millions into developing the financial models (or GPT-like models) - you are welcome to release them into the public domain if you wish. However you don't get to dictate what the people who have actually invested the resources get to do with them, including what conditions they attach to who can be exposed to it (a la the non-compete). As an adult, I retain the option to not take the job with the non-compete.
