This is only partially true. Even if there was a successful miner activation of any soft fork, there is a minimum threshold of nodes required to update to prevent a chain split. Miners fear chain splits and would be highly unlikely to push a soft fork that would create one because they would cause big problems and reduced revenue for miners. We saw this play out during the blocksize wars.

Thats not true at all if that were true segwit 2x would have easily been included into the chain, the sad truth for morons who don't understand how Bitcoin works is that economic nodes control Bitcoin not mining nodes. And the economic nodes are made up of a decentralized majority of long term hodlers who dont like to pass through bullshit because some centralized dev team told them to.
