Okay, so I saw the slides. I figured someone then took them and presented them as their own work. But no. The video was a bloody review!
How on earth is it possible to shut one's critics up by using/abusing copyright infringement claims? Well, the answer is obviously YouTube who always - always - grant any claim to the detriment of uploaders. I know this from personal experience and have had several videos wrongly flagged for this and that.
From the title, this was clearly a review - not theft. It is quite franky infuriating and this ridiculous interpretation of copyright needs to be flushed once and for all.
