I believe there charges shows not only well intention but also that Facebook actually cares about and listens to the community, which in the long term is many times more valuable for the ecosystem then this particular change in itself.
Great work!
Great work!
Changing the license because people are leaving the project only shows that FB cares about itself.
Claiming that you decided to change it out of the goodness of your heart seems a bit disingenuous. I get if you needed to clear it with the lawyers/business owners over that time but claiming it was changed on a whim doesn't ring true.
