Yan Le Cunn has talked about Meta's strategy with open source. The general idea, is that the smartest people in the world do not work for you. No company can replicate innovation from open source internally.
Of course, i am not arguing that. But when it comes to software as general as code generation, or text generation, the possible applications are so broad, that a team of A.I. researchers in a company, however talented and productive they are, cannot possibly optimize it for every possible use case.
That's what Yan Le Cunn is referring to, and i agree with him. There are a lot of companies which push deep learning forward, and do not release their code or weights freely.
