Why would other instances have to move away to the corpo protocol? I mean, if they screw them over by creating a walled garden in the fediverse let them do whatever they want. They have absolutely NO power about my self hosted instance and the instances I federate with no matter how big, important or powerful they are. If they break the protocol by injecting harmful content you can still stay on an older version or fork it. Its open source for a reason.

Also if the average joe moves over to the corpo platform: it's their decision. The only thing I can do is provide an open and transparent alternative and inform people with my conviction. We have to give up the idea of hoarding users and forcing security and privacy on them no matter how well we mean it.
