Shorter version of this guy's video:
Silly women, boycotts never work! Don't you know ads appeal to emotions? Companies don't care if they are seen as misogynistic and you don't buy their projects. You should do what I tell you instead. I'm a random guy, so I know best.
You could watch the video and realize that I said if they want to fight sexism, this isn't the way to do it, because the advertisers know these women aren't buying their products.
