Protest needs to be disruptive or inconvenient in some way to draw any kind of attention or have an impact. Otherwise the complaints can be entirely ignored, but that often seems to be the goal of corporate-sanctioned protest; get everyone who is angry to channel their energy into something time consuming but utterly ineffective.

Categorizing a publicly organised protest tactic as a "cartel" seems like a stretch too, especially when on the other side we're looking at a company in a market with maybe three or four major players? If one was casting an eye for cartel-ish behaviour one should probably start with the major cereal companies, before going after a bunch of randos on Reddit.
