As your link says, "Betteridge's law of headlines is not always true."

The evidence presented seems persuasive, though of course it could be cherry picked from a small number of polls which go one way when most polls go the other way. I don't have the background to judge.

However, with the increasing call to 'run a government like a business', which includes the rise of charter schools outside of democratic control, I see no compelling reason to disagree with the thesis.

Why do you think it's incorrect, other than the construction of the headline as a question?
