Ad-blocking is turned off by default in most browsers. Also basically no one wants to see ads, it is functionally useless, you can just go search for the thing you want to buy. Censoring someone because you think they are harmful isn’t similar to this. You can develop a trump-blocker extension but having this enabled on default in a browser like chrome would be obvious censorship
