Actually, blackmail is the coercion of a benefit derived from the act of a threat. Twitter clearly threatened the city along with a number of other startups in the SF area to move the jobs and tax revenue to another local town or city if SF didn't abate their payroll taxes. Thus, blackmail is a justified and correct term for such an act. But, I will concede that coercion is an equal substitute. While I don't fault twitter for their business decision. I do find it fair to call the kettle black when it is true. I generally don't have a problem with companies tax planning within the means of the law to achieve their tax goals, but simply flat out threatening the community that created you doesn't seem 100% fair either.
