The underlying issue they are trying to solve is that developers believe they should be able to extract some of the wealth they feel they created. In open source, that wealth is often only created because the software was free. Otherwise, people would have used something else that was free but worked well enough. Developers like to often argue this isn't true, but history shows it to be true basically always :) So saying you should be able to extract this wealth is probably wrong. Saying you should be able to get paid a reasonable amount of money is not.
