Yup. Citizens United wasn't a "is money speech case?" It was a case about whether the government could ban an unflattering movie about one of the leading candidates in the election. Its core political speech and always has been.
Whether or not you agree with the slant of that article, it is a fact that Super PACs have enabled a massive centralization of political contributions - which, even if there's a limit on how much advertising can accomplish in general (cf. Trump), is still fundamentally undemocratic, and should be fought. We probably can't just go back to how things used to be, so how do we go forward?
