He's interesting a CEO to attract ad revenue, and take the blame if they fail. And they'll fail because the gap is too big at this point.
I loathe Musk and Twitter, but I actually don't agree with this prediction.
If he's hiring Yaccarino, it's going to give advertisers an excuse to get back on Twitter. I don't think they genuinely care about the politics or whatever, but the optics are bad for them. The optics will get much better once Twitter is run by someone who understands how PR works.
But you'll probably see plenty of "follow my account for feet pics" ads and so on smaller advertisers pick up the slack. Hey maybe that's an undiscovered gold mine.
