Musk and the people backing all this are more interested in reshaping the global order than in earning fake “fiat currency.” Their real goal is to usher in “hard currency” and re-base global currencies around scarcity and physical assets. So no it really doesn’t matter much what happens to Twitter’s ad model in the meantime. It will probably do alright, and they can probably find other ways to make money, like adding in payments and weird Dogecoin schemes.
Yeah, this article by Dave Troy from last October was not only prescient but has timely reasons why Twitter and Bluesky might not be the competitors you think they are.
