In the cases that Roger (bitcoin.com ) and Jihan ( ant, via, and top ) are not state or corporate interest backed this attack is costing them lots of money/losses.
attack?
non-core implementations have been running for years and have no intention to ban and split the network controversially/bilaterally.. otherwise they would have already.
also they would have set deadlines and added code to intentionally split the network.
however non-core devs have just run as normal, no threats no banning/split code.. all they have is the usual bitcoin consensus code.
it is core that fear losing their stronghold and having to either drop themselves down to a decentralised equal playing field with the other diverse nodes or split off and have a core only network. and we know what they prefer.
remember core did not exist before 2013. core is not the sole implementation running bitcoin.. but they want to be.(thus removing diversity)
they have been desperate to rock the boat and try poking the bear to get non-core teams to split. but those other implementations refuse because they understand and want diverse decentralised bitcoin to survive. not hand power to only core by walking away.
wake up to the bait and switch of core pointing the finger the other way for their own intentions just to play a fake victim card when core pull the ban trigger to cause the split
