Twitter is not a growth company by any metric: Users, revenue, or stock price. If they could easily generate lots of revenue right now with their current management, they absolutely would already be doing it.
If Twitter is losing $180 million per year, and they have 7500 employees, and each employee costs on average $100k [0] fully loaded ($750mm/yr), you could become profitable by reducing your payroll by 50% (laying off half their employees).
My guess is layoffs aren’t considered as an option since it would signal that they’re throwing in the towel and don’t believe in their own growth trajectory.
