The article makes it sound like the answers are "yes" and "yes"; but I'm skeptical. I suspect the answer is that there's no real problem here with racist rants and the like.
Instead, this seems like a blanket policy that helps keep research from going in directions that lead to uncomfortable (politically-incorrect) truths. That sounds bad for science.
Then again, I assume this will mostly apply to social sciences, which don't have much respect to lose.
