I'm neither a fan of advertising nor Trump, but this reads like yet another patronizing think piece about how the wrong people get a vote and it's terrible that they use it in ways of which the author does not approve. "If only there were some way to control what these people say and hear, we would not have such problems as Trump."
The problem with controlling the flow of information, besides being morally reprehensible, is that it leads inevitably to ignoring problems that do not directly affect or concern the gatekeepers, like rural economic devastation. As well, these censorious advocates always imagine the mechanisms of control will only be used by people they agree with, never imagining the mechanisms of control will be used by their political opponents.
The author later reveals the agenda:
> “But it's free speech!” Bullshit. No one is entitled to yell at you “GET 20% OFF THIS UNDERWEAR YOU GLANCED AT YESTERDAY” with a dopamine megaphone in your bedroom. And to track 90% of your life to know when and how to say it. That's not free speech, that's harassment.
A fair and honest reckoning with the question would acknowledge the problems such a ban would introduce with free speech, not simply dismiss them as he does here. If you make a thing, and then you tell people about the thing, then you transgress against the advertising ban. The idea is nonsense.
