Reason being, look at Tesla stock price: Musk's gaffes have a short term impact, but overall the price is way up since buying Twitter.
Musk used to dabble much more in Tesla directly than he's now, I wonder whether the ups and downs of the company correlate with his involvement, especially before he started going off the rails so badly? That would be informative and help separate object-level impact from political hysteria.
Tesla is absolutely in the advertisement business.
Their marketing and image is the only thing holding the company up (for now).
We can argue the first part all day. The point was Coca Cola and co. did not want to assossiate anymore and that had an objective dollar amount.
I know less about this situation, but Twitter in 2024 apparently made some controversial blocking changes and that started the bluesky migration. I don't know the dollar amount there, but they apparently lost some big influencers.
I mean, why do people who hate what Twitter is now care about it's lost revenue? Especially given what it was, and where the revenue came from, this isn't exactly an argument that generalizes well.
