a permissionless version outside their control and was meant to either try to take over the main client of the uncrippled chain ("fulfilling Satoshi's vision"), or to disrupt the chain

Any other chain which will stand a real chance to be uncrippled will suffer the same fate as BCH.
This isn't a conspiracy theory, it was done in some well known examples when standards were crippled to decrease their disruptive potential (e.g. https standard).
