The precedence is very real, and it's gone on for years. Companies will up and relocate when it makes fiscal sense. Boeing, for example, was headquartered in Seattle for decades -- very established, entrenched locally, big production plants nearby. Chicago came along and offered serious tax breaks if they would relo HQ. This isn't down the road -- it's Seattle to Chicago, involving something like 1000 employees and their families. Boeing took the deal and gained millions in tax concessions. At the time, Twitter did an evaluation of payroll & stock option taxes and determined that it would be worth a lot of money to everyone (it's not just the company, it's the people) if they have a shop outside SF geographic boundaries. Pick up and move down the street? Yeah, easy choice.
