Since bitcoin is a decentralized system, who's decided that segwit2x isn't going to be deployed?

user5406: Key proponents of the New York Agreement have rescinded their support after large parts of the community opposed their initiative for months. Theoretically, a miner could still activate the fork unilaterally, but the expected value of the Segwit2x network dropped significantly with the exit of said key proponents.

user35: Though its major proponents have called it off, there's a miner with an unknown (likely less than 10%) amount of hash power vowing to continue: https://cointelegraph.com/news/segwit-death-challenge-bitpico-vows-to-fork-as-bitcoincom-goes-100-bitcoin-cash
