I agree that open source (or source available) is better, in particular the weights and code, the training data is immaterial. But I think a lot of this is pretty naive. The "best" model is the best and it's unlikely to come from some idealistic consortium. And the data they have is virtually irrelevant, as every company that thinks they have a great trove of data finds out. My recommendation would be to use whatever the leading source available models is (one of the big llamas?) and focus on the guardrails needed to make it a helper for medicine. Reinventing the wheel is a bad idea.
