Probably why they just canceled on their Seattle expansion too they found how much the municipality will sweeten the already gooey pot if they threaten to walk away.
Here in Seattle Amazon canceled expansion in Seattle proper but is purportedly moving 10 to 20,000 existing jobs to Bellevue which is across the lake and about ten miles east of Seattle. Bellevue is a more business-friendly city and moving the jobs will alleviate the Amazon traffic from the east side neighborhoods into Seattle. The east side has housing that is better for those workers raising families and not wanting to live in the downtown Seattle beehive housing.
Amazon will occupy the Expedia building in Bellevue. Expedia is moving its operations into a slightly north location in Seattle.
