Facebook should not have to pay any taxes as it gives to the world an essential service. If Facebook was made to pay taxes it might have to charge for the basic human right of "liking" 1980s breakfast cereals or telling everyone of your 19,375 friends that you are in a relationship but "it's complicated." That kind of service deserves a tax refund. After all their stock sucks so cut them a break, or maybe you don't want to know what your arch-rival in middle school is doing at each minute of the day.
I think every one of us who feels this is disgraceful should boycott facebook.
Or better yet, short their stock.
