>Citizens United doesn’t have anything to do with lobbying. It’s about companies spending their own money to air political ads. If Intuit and H&R Block were running ads trying to convince people to vote for politicians who support complicated tax filing, then Citizens United would be relevant.

While this is true in the literal sense of what the case was about, I find it disingenuous to claim that this is the only impact it had. The rise of 'Super PACs' is correlated directly with the decision. Here's an extract from Wikipedia for instance:

>Certainly, the holding in Citizens United helped affirm the legal basis for super PACs by deciding that, for purposes of establishing a "compelling government interest" of corruption sufficient to justify government limitations on political speech, "independent expenditures, including those made by corporations, do not give rise to corruption or the appearance of corruption".
