There's more than redistribution happening here. Co-pilot is providing a value-add service where the open-source code is an input and the output is a service. As it happens, the service is actually regurgitating the code at this point, but it's important to consider that even if it didn't regurgitate the code verbatim, the fact that the service is making use of that code to provide a value-add means the code is a crucial input to the value proposition. Would Co-pilot be able to provide the value-add without the source? Likely not. Couple that with the fact, that presumably at some point in the future, Co-pilot will come attached with a subscription model (otherwise why do it in the first place?), and we have the makings of a product that is commercially infringing on copyright left, right and center.
