Donating to a candidate or sponsoring an ad that says things about a candidate are protected political speech, requiring a strict standard for the Congress to regulate. Citizens reasoned that if that’s true individually it should be true for a group, on the basis—in part—of freedom of assembly, whether that be an advocacy group or corporation.

Money = speech is a colloquial but wrong summary. Money donated to a candidate or used to buy speech is protected, whether done individually or as a group. The simplest resolution is to read the opinion.

(Logically speaking, it makes sense. It’s just absurd to construct the freedom of assembly as automatically making all rights natural persons enjoy commutative.)
