The real problem is hidden in the end of the "article":
In another instance, a person watched a video about software rights and was then recommended a video about gun rights. So two rights make yet another wrong YouTube recommendation right there.
In a third example, a person watched an Art Garfunkel music video and was then recommended a political video entitled “Trump Debate Moderator EXPOSED as having Deep Democrat Ties, Media Bias Reaches BREAKING Point.”
So what is the problem here? Recommended videos aren't just based on the previous video watched. It is based on a profile of you. If you are interested in software rights, you might be interested in gun rights, or human rights, or something similar.
Albeit, in a number of the examples cited in the report, the confusion is leading YouTube users toward content with a right-leaning political bias. Which seems, well, curious.
Ah, NOW we get to the crux of the issue. We get it guys: you want to stifle any expression of what you consider "right-leaning". Do not pretend that you are scientists, doing a study. You are a bunch of Millenials who installed a browser extension.
