YouTube, afaik, doesn’t just let advertisers blacklist individual channels.
I see this sentiment all the time and I just don't understand it. If I sold razor blades, or if I was Stephen He's dad and sold Beijing Corn, I would want EVERYONE buying my product. Communists, Fascists, Russians, Ukrainians, Israelis, Palestinians, Antifa, Proud Boys, Prince Andrew, Andrew Tate, etc.... They may all hate each other but they should all agree that I make the best damn razor blades / canned corn on planet Earth, and everyone should buy it.
This weird era of conspicuous consumption, "lifestyle" branding, and virtue-signaling faux-activism can't end soon enough.
This weird era... See this is what blows my mind. Like boycotts are not something that's happened pretty much forever. There is currently a particular group that has been bearing the brunt of boycotts due to their socially unacceptable behavior and they seem a little ticked that the power they once unilaterally wielded is now leveraged against them.
It's sort of amazing that the biggest search company on earth can't filter/select ads like that.
