Think about Space X. That is company full of engineers who are 100% dedicated to the job and to the success of the business. Twitter isn't that but it is Elons plan to get it there. If there are 500-1000 employees who just want paychecks, you don't work there anymore. He wants to make Twitter the social media Space X. He is doing exactly what I would do in his position. Well except for firing that one dude...
