Ah, now we're on the same page.
Thinking about it, I could see how he underwent the audition, thinking the "you may opt out of the usage of the footage" clause just being plain lawyer talk. After all, he could never have expected that DT would produce this soap opera style documentary out of it! So, suddenly he sees this documentary and is pissed that they didn't even check. with him. Legally it was OK, just not the nice way. From DT's side of course understandable too, why ask if the answer could be no?
So, I can see your point of him having underestimated the thing (what you called "naive"), but DT doesn't come off clean either. They knew from the beginning they were going to produce this documentary out of it, and thus pulled wool over the guys' eyes regarding their intentions with the footage. That is "the business way", but I also fully understand Marco being pissed about getting duped by DT that way. You go into an audition thinking the camera is for the band's review of your performance, but in fact it was always meant for the documentary.
