They are moving there are they not?
1500 workers, not their HQ2.
They originally only committed 700 jobs.
HQ2s don't build themselves overnight.
The threat to move the headquarters was nothing more than an attempt to get concessions elsewhere.
They weren't moving a headquarters, they are building a new one.
And no headquarters is going to employee 25,000 people.
They have over 50,000 employees in Seattle.
If they hire fewer than 25,000 their tax break is smaller, AFAIK
