A good marketing department should display things in a positive fashion, but they should also strive to be honest, so they're not loosing credibility.
I recall GitHub doing some extensive research on what their customer based wanted. This is most likely the outcome of that research.
If I were to migration our org. over we would be worse off. Even with that I don't think this move is disingenuous. Poorly thought through perhaps?
I never said that I consider the move disingenuous. Almost no change will unilaterally benefit everybody. I dislike the communication that reads as if the change is unilaterally beneficial - where it clearly is not.
And GitHub is also allowing everyone to make a choice. "...you'll have at least 12 months notice before any mandated change to your plan."
