If my code is included in a training set which then helps someone else solve a problem, then I am helping other people. Why should I care if some 3rd party is the middleman that builds the system that performs the transformation? I put out my code so that people can use it. The existence of said 3rd party doesn't restrict that in the slightest, in fact it enhances the reusability of my work which seems like a win-win.
