"Brand Bad" behavior of people who promote the idea that only a "brand of information", source, author is credible. Who do not wish to fact-check and scrutinize each idea, but instead declare "Wikipedia is a bad source" (trying to dismiss the entire brand of source, instead of teaching that fact-checking citations and references is important no matter the source).
A form of nut-picking, were entire ideas are dismissed and thrown out because of mistakes, errors. And people who do not seek common ground in joining / merging / coming together with the best possible understanding - but instead want what "corporate overlords" desire among consumers: Brand Loyalty to a source / brand-mark.
A common example in USA is Rupert Murdoch's Fox News - where there is a constant emphasis in content that other news sources are all bad brands, and Elon Musk does this with his X media platform too.
