“In speaking to Amazon, they don’t lay the blame on any single entity. They realize that there was political opposition on every front,” she said in an interview. “And that is because this is a flawed process. The process should not get two years down the road, practically, before you actually bring in the community.”

City Council Speaker Corey Johnson

Mr. Johnson had applauded Mr. Gianaris’s efforts to block Amazon, and he affirmed his criticisms of the company on Thursday.

“I hope this is the start of a conversation about vulture capitalism and where our tax dollars are best spent,” he said in a statement.

Unions

Opponents to the deal constantly pointed to Amazon’s anti-union reputation. Amazon officials said at a recent hearing that they would not remain neutral if their employees tried to unionize.

But the city’s unions were divided on the deal, and their reaction to its collapse was equally split.

The Retail, Wholesale and Department Store Union, which had vehemently opposed the deal — Amazon presents a direct threat to retail workers — said the company had taken an unacceptable, uncompromising approach.

“Rather than addressing the legitimate concerns that have been raised by many New Yorkers, Amazon says you do it our way or not at all, we will not even consider the concerns of New Yorkers,” Chelsea Connor, a spokeswoman for the union, said.
