As far as I can tell, we actually have no way of knowing that the NY variant doesn't spread more easily than other variants. There just isn't the data to disentangle whether that variant became more widespread because everyone did a worse job of stopping that particular set of cases from spreading, or if everyone was less successful because the variant in question was worse. We'll probably never have a definite answer.
