I'm naive about business but I just don't understand what Twitter even needs a LOT of money for. Yes, they need some funds to run servers, update apps, and the usual internet company maintenance...but it's not like FAANG companies, which have a lot of ancillary products and services, many of which are big and expensive risks...but that's what investors signed up for, an ambitious innovative mission.
