The content moderation clowns and VP of user engagement are the ones who are making sure General Motors and other customers spend the millions of dollars a year on advertising. There's a reason that at pharmaceutical companies the people who make the most money are in sales, not the people producing the medicine.
We just started doing advertising on Twitter this year and have spent over $100k and probably would have spent more next year, but there's a good chance we pull our advertising because the chaos is bad. The content moderators are the ones who ensure our ads aren't placed next to racial slurs of other content that could negatively affect the company. The account managers are the people who make sure our issues get resolved quickly. Those are people that are cut. So sure it's great to save $300k by firing the guy who's managing our account and some content moderators, but if us and the other 9 accounts he's managing all leave then that $300k savings just cost you $1 million. If even 4 of the 10 someone is theoretically managing left it would be a net loss and they are losing more and bigger accounts.
But clearly companies like Facebook and Google cannot make any profit off of primarily advertising revenue so Twitter needs to be more like letsrun with their revolutionary subscription model where they are just rolling in piles of cash. (Honestly, Elon is only 80% a moron, he probably knows he can't rely on advertising if he wants twitter to be a cesspool of hate speech so he needs a different revenue source. He just has no idea what that is and the idea of charging your most popular users is the dumbest ever.
It's like Netflix charging movie/TV producers for having shows on their app, why would anyone agree to that? Twitter already has a great deal where users are creating free content for him. If he wanted to charge users for an add free version of Twitter that might be more palatable because A) there are a lot more users than blue check people so there is more revenue possible, and B) they are actually getting a benefit from it potentially as it would improve their service.
If you want to charge content creators, the best way would be to provide tools for them to monetize their feeds and take a 30% cut or so like Apple etc. But if you feel like you are smarter than everyone else in the world and you surround yourself with people who just feed your ego, then you make some dumb decisions.
