She didn’t kill the deal; it was turning into a PR nightmare for Amazon, but as I understand it was really convinced them to pull out was that local politicians opposed to the project had been seated on boards/committees with which Amazon would have to work for permits, variances, and such. At that point, they realized it could be tangled up in red tape forever, so they withdrew.
Cuomo seemed to understand this when he blamed a whole group of local politicians - and probably didn’t have Token PR in mind (she wouldn’t have been involved in those aspects - and it wasn’t even in her district anyway).
Don’t forget about the New York unions.

“Hey sonny - nothing gets moved off these docks if they ain’t no union present, and I don’t see no union.”
