From what I heard, Google also doesn't get the kind of deals with tax breaks that Amazon did. Amazon wanted to leverage their added value (which is clearly existing) into some benefits. That did not work in this case, but it wasn't at all obvious it won't. Majority of New Yorkers supported the deal, as it was.

Also, "nobody bats an eye" is not right either - there are tons of protests against Google, which has been widely reported. They just didn't have a focus point like Amazon did, but if any city had a wide contingent of young socialist politicians caring about PR much more than for the jobs for the city population - the same could happen to Google too.
