I agree this is definitely possible, but if you do all that, is it still the public square open to debate, if you are selectably promoting / monetizing "tasteful" tweets?
Plus, you can look at most biased news sources and see the drama that they selectively cover under the guise of news. "1 person did a bad thing" and "here's another reason why this entire group is conspiring against you" are not uncommon tropes.
