It's not so much copyrighted material as it is product placement. That's why the Nerds Rolling Rock is sans label. I have a feeling Youtube is just covering their backsides from potential lawsuits. I mean there is a butt load of people on the tubes I wouldn't want to be affiliated with any products of mine.
That and there more than likely is a clause that makes Youtube pay a licensing fee for any products appearing in a video that is monetized.
As far as Nintendo is concerned. Douche move, yes. Do
I care, no. These guys sit in their houses and play these games at their
leisure. Youtube reviewers are the same. I don't consider this work, period. I realize paid network reviewers on a
deadline are very different. I mean having to crash through, say an 80hr game in just a couple of days is a pain in the ass. At this point it becomes laborious.
I fairly sure most, if any LPer's don't actually have the rights to the games they are putting up for display to the public. So they might as well get used to that knot in their panties. Whether it be man panties or woman panties.
