Quoted from Xenon75:some people can't maintain their own opinions or things they like without validation from the herd. so for them its major cognitive dissonance when they see a Top 100 that doesn't match the list they have in their head.
You just summed up all social media and how algorithms are ruining everything. 
The ones complaining are used to living in echo chambers and blocking things that they dont like so they end up living in this weird disconnected from reality sanctuary. Only seeing what they want and only hearing from others that support what they want.
