Reading the report, this wasn't actually a random sampling of typical users. They used opt-in reporting from a self-selected group of volunteers who were interested in reporting "regrettable" YouTube recommendations. If some of these users were deliberately scouring YouTube for objectionable content, it follows that their recommendations would start matching similarly objectionable content for them. After reading the report, I don't see how any of this is representative of a typical user's YouTube experience. It certainly doesn't resemble my own experience at all.
