I don’t get it. I watched the video and there is nothing remotely controversial in it. It was actually kind of boring.
There has to be more to the story. This stuff is pretty mild compared to a lot of YouTube videos out there. YouTube has actually been very good about refraining from censorship, pretty much removing only those videos that violate copyrights, prohibitions on porn, excessively violent content, or advocate or instruct blatantly illegal activity. And they've left their comments sections almost completely unmoderated.
I wonder if Attkisson got flag-bombed? YouTube employs a small army in the Philippines who do nothing but comb through videos, removing those that violate YouTube's TOS. However, I wonder if they have software in place that automatically removes videos after receiving a certain number of flags?
