Blockstream kicked out the teams from Bitcoin ABC, XT, Unlimited, nChain, BitPrim and Classic. They kicked all the nodes out that weren't running Core and they revoked all of the developers and stopped their nodes from confirming blocks.
Then Blockstream created a new coin with stripped-out digital signatures, created Segwit Coin and got CME, Gemini and the regulators from NYC to agree that the new coin would retain the XBT/BTC ticker. It was basically a coup d'etat. Even Coinbase and Bitfinex said they would support B2X if it would stop Blockstream from cutting out every other developer from Bitcoin. That's also why they were slow to activate Segwit. They were all against the coup d'etat against the original Bitcoin chain and the removal of all dissenting developers and nodes.
You don't think it's bizarre that in 2017, there were like 10 teams of Bitcoin developers working on Core, and in 2018 there's only one team and everyone's keys are revoked if they aren't a Blockstream employee?
You are clearly rewriting history, I followed everything very closely and this is not what happened. You don't see how well Bitcoin is doing now Segwit is implemented? This is blocked for more than a year by guys like you. Go investigate and learn about consensus.
