The opposition to 2x is not led by Blockstream. Nearly every prominent bitcoin developer objects it strongly[0], not just the few that are Blockstream-related. My own company, Bitrated[1], objects it strongly as well[2].
Also, many of the major bitcoin exchanges, wallets and businesses aren't signed on the New York agreement [3]. Segwit2x doesn't have as strong as a consensus as its supporters try to make it appear.
