That is not quite fair is it?

Publicise your work as open source and make hay with the work of open source contributors who thought they were contributing to a truly free and open source project only to find out a couple of years later that their contributions are now locked into a project that locked itself up with a changed license... (I know that their contributions may stay with the license it originally was, but if the total product changes license, who is going to continue an unmaintained fork? )

IMO, it is fair criticism when someone starts off with a liberal license and then changes it when it is time to monetise, or someone else figures out how to monetise it better than the creators. Either be okay with it or not, you can't have it both ways.
