My issue with this term being applied to this situation is that the timing and context I think are off some. To provide a comparison within the same subject:
Amazon moved up the release date for the Walter Issacson book pretty much the day after Steve died. Released it a few weeks earlier than orginally scheduled, if memory serves. To me that is vulture-istic and the epitome of opportunistic.
This movie: Literally years after the mans passing, it's being released. I'm don't deny they want to make some money off of this movie, but with the amount of trouble in the beginning, they decided to see it through when they could have easily abandoned the project. I think there was some passion invested in this project that goes beyond a paycheck is my point here. Not just an opportunistic payday, imo.
Another conveniently forgotten fact: Steve hand picked Walter Issacson to write this book. If memory serves correctly that was partially due to Mr. Issacsons reputation to tell it the way he saw it....and Steve I believe wished for a factual portrayal even if it meant not everything was flattering. Mr. Jobs got exactly what he wanted and intended for that biography, and I don't mean that as snarky as it reads typing it.
