I meant the LLM weights are not publicly available in the case of ØpenAI, so whatever you contribute to it will be locked up, just like SO locked up their user-generated data.
With Stack Overflow, everybody contributed to their data set. This data set is centrally managed by Stack Overflow and access is whatever they choose to allow. When they block access to that data set, it effectively takes it away from the public.
With OpenAI, they aren’t locking anything away. They are analysing the data and adjusting the weights in their model. They haven’t stopped people from accessing the data they are training upon.
What Stack Overflow are doing is stopping the free flow of information. What OpenAI are doing is providing an additional channel for it to flow through.
