As somebody whose name is in the credits of the 3rd edition book and who has worked with WW and OP over the years on each edition of Exalted, I'll say that I would take all of that with a grain of salt. When OP found out I didn't have a contract because of how things were handled at a level below them, one was sent to me immediately and I was paid for all of the work I was credited with.
As for the allegations that WW/OP pays significantly below the industry standard, that's not my experience. The industry standard as a whole is pretty terrible. But that gets into the whole, "Are RPGs too expensive/etc."
OP has always dealt with me fairly and honestly. I also have every faith the new developers are going to run things right insofar as freelancers are concerned. And I say this as somebody who has no plans on ever working for OP again.
