1) This is by any source I can find, incorrect. Twitter had ~8,000 employees when Musk bought it. After layoffs that was trimmed to a low of around 1,500 employees (19%), and today it has around 2,800 employees.
Also worth mentioning that a lot of Twitter's products are built on X.ai which has 1,200 core employees on Grok with 3,000+ on the Datacenter build-out side.
Also if you put a product in maintenance mode you can easily get away with a fraction of your devs. Most people are at all times working on some definition of something new
Also have to consider that it’s now private which removes the pressure of having to show any semblance of a profit or, critically, share usage or advertising statistics which could (and probably are) down dramatically since the acquisition. Being private allows the fictitious storyline to persist that “we’re doing great and everyone is using our products.”
