It sounds more like they are "controlling" centralized fiat exchanges instead of Bitcoin, but don't let that stop a sensationalist title.
Sorry, Charlie, we accept only the finest tuna and your post is not it!
New York regulations would cover all exchanges, no matter where they are located because if the exchanges wanted to do any business at all in New York, including sending or receiveing fiat or crypto, the exchanges would have to conform to New York law.
My $.02.

To be fair- the United States does not dictate what other countries will do with regulation (although it may influence it in some cases). I'm betting most people here aren't American or US based- so when you say 'all exchanges' that comes across as fairly sensationalist to someone living elsewhere. The thing that I love about Bitcoin is that although the US will influence adoption, it does not necessarily need the US to drive adoption to succeed- and that's the beauty of a decentralised currency- you can regulate locally, but it is impossible to regulate the whole, internationally.
