because there people who do video game commentary  for a living and also people who like to watch reviews on video games or watch interviews of the creaters and publishers of video games it helps people decide rather if they want to buy the game so those reviews and interviews helps the video game creaters and publishers make money there cases where maybe the people wern't intrested in the game then watch the videos and change their mind and there company's out there who think these video game commentator's showed be allowed to continue what there doing and if youtube deicdes to keep these polices then there gonna hurt both the company's and the commentator's which would make youtube less popular and make commentator's have to find jobs which in this bad economy where in it's hard to find jobs
