I'm not talking about boycotts in general, like say the Montgomery Bus Boycott, because we know those can work. I'm talking about "Company that sells product made me mad" boycotts.
Whether it's past ones like the infamous Call of Duty: Modern Warfare 2/Left 4 Dead 2 boycotts, or more recently like the brewing chud Pride Month boycotts (And if we're being brutally honest here on the flipside: The all-but-in-name boycott of that Harry Potter game a month or 2 ago), all of them seem to universally fail spectacularly and not impede their targets in any way.
Nonsense. The game disappeared from conversation because it was mediocre and utterly unremarkable. That boycott was especially useless because it only managed to deter mid-sized streamers that were small enough so that the boycotting crowd could actually affect them, it barely deterred the real big 10k+ view streamers at all.
