missteps or not. He has cut a billion dollars or so of expenses in just staff and also reports Twitter users are going up, so I’m hesitant to paint things with a broad brush of failure (as you seem excited to do) by looking only at a single report on advertisers.
Specific to the article you linked it might seem a bit biased if it is using language like “rash of brand unsafe actions — including amplifying conspiracy theories, unilaterally reinstating banned accounts such as that of former President Donald Trump, courting and engaging with far-right accounts.”
Not surprisingly, if you go to their site every article on the front page has a hard left slant to it. It appears far from an unbiased entity, and certainly appears bent on demonizing conservatives or those not far left.
Anyway, carry on, your position of disliking him is clear and that’s fine. It will be interesting to see if twitter turns out to be a flop or not.
