The thing is... This whole debacle paints the writers as victims of ignorance, while OPP was more than willing to take what was serviceable. Still:
Through the freelancers involved likely feel crapped on (and that may be the case) and part of me "feels" for those guys, the fact that Holden doesn't put together that 90K words here and 150K words there, says more about his (speculation) abilities to produce what OPP wanted/expected, than it does about OPP "nefarious" business practices. There is also a freelancer on the Facebook post who redacted her work from OPP, but it isn't clear why.
I had my own mini-tantrum with Palladium Books. But, when I had a bit of time I came to realize I allowed that (unfortunate situation) to happen, just as much as Palladium facilitated it. Admittedly, my situation wasn't at the scope of what is here (not even close), but it sure smells similar.
