Loud, blatant lies that are repeated by authority figures continuously is one thing. That this is bad is almost universally agreed on. But does this advertiser worry really stop at that?
I think this is a very interesting question, hitting at the heart of the Twitter controversy. Advertisers have an incredibly strong influence on contemporary discourse; their concerns influence almost all publicly-visible discussion, opinion and debate. The attention economy, eyeball-and-click-hunting is just the tip of the spear, and this dominates almost every public communication platform in the world.
Elon Musk and his $44 billion «fuck this shit» purchase is the only significant challenge to this model. It will obviously upset the advertisers; it’s tautological.
Maybe the result is that it won’t work, but if it does, Twitter will be the only public communications platform that isn’t very heavily influenced by advertisers’ interests.
