"Hey guys, gamer boycotts don't work, just look at this screenshot of a Boycott MW2 group on Steam."
Incidentally by the way, that screenshot is one of around half a dozen groups, might not have even been the biggest one, doesn't show the 16+ other pages, doesn't tell us if people were trolling them, and doesn't include the context of later declining CoD PC sales.
"But wait, didn't boycotts against things like Always Online DRM for the XB1 and paid mods work?"
"Sure, but other than those extremely effective examples, gamers are just too weak-willed to boycott. Didn't you see this funny JPEG proving that?"
"So, if boycotts don't work, if we buy a game and it's bad, we can at least just review bomb it right?
"Don't do that, that's childish and uncivilized and harmful to devs."
"So you want us to just boycott quietly?"
"Yes."
"But you just told us that boycotts don't work."
