What does that even have to do with anything?
Twitter is not really that much more complicated than a forum. Sure it has to be designed to be scalable but that work is already done, it just needs to be maintained. You don't need 10,000 people to manage that. Their entire infrastructure probably fits in a small data centre like say, 2,000sqft or so. Maybe two in different geographical locations for redundancy. If they really wanted to downsize they'd have a couple IT techs at their data centre(s) for physical tasks and everyone else working from home, most of those jobs can easily be done from home.
These people were mostly just lounging around eating company food on company time and getting a bit of coding done in between. Place looks more like a daycare. It sucks, but it's not like it's the first time a company does mass layoffs when they see inefficiencies. People are just being butthurt because it's Elon doing it. If it was any other person people would just be saying "tough luck, guess they need to find another job".
