Even if you assume that somehow 50%ish of employees do literally nothing at Twitter, the people that remain will still have much more work shoveled on their plate for the same pay. Actions like these are a great way to completely kill a company because no one wants to jump to a ship that's currently on fire.
I would join Twitter after a 75% culling if the stock grants and pay were proportional with the risk taken. Culling 75% from sales and marketing departments is easy. It’ll be harder in engineering.
