That seems… implausible? They used to be profitable; clearly at that point advertising revenue must have greatly exceeded infra cost. Now, I’d buy that it’s down, but surely not by _that_ much.
Oh, sure, I’d be amazed if it’s profitable today. But I understood the person I was replying to to mean that they were throttling to control infra cost, which makes no sense, as revenue from people using twitter (ads) must surely more than pay for the infra; effectively shutting down twitter won’t make the debt costs go away and would clearly be a net financial negative.
A lot of advertisers left Twitter one after another after each change by musk. Especially his change to allow hate speech (because free speech!) led to an exodus.
Now there are only very low-quality ads by drop-shipping companies left. I bet they don‘t pay as much as the big brand names before.
