There's a free speech issue to saying "you can't advertise your own opinions". Where is the line? Should every charity that "raises awareness" be banned? Should every sponsored Youtuber be forced out of political commentary? (I mean, I don't hate the idea completely ....)
There's the skeezy links behind organisations that support a political stance, and claim no real links to politicians. But we know that it's all kinda bs with strong links between the "nonaffiliated" "Political Action Committees" that claim to just represent causes and ideas, and the politicians who just happen to be close friends with the organisers. But it's rarely totally black and white.
