Hi J,
You are correct that this is a big challenge. The BPs are moving to renege on the Constitution. It is the case that it hasn't been put to the referendum, but actually, that's not a problem as far as the BPs are concerned: the Constitution is the document they agreed to, and it remains in force until replaced.
The fact that the BPs are withdrawing from an agreement they agreed to - unilaterally, or as a group without consent of the community - should tell us most of what we need to know.
Clearly, if their rebellion works - if the BPs are able to remove the Constitution from EOS, then the victors will declare the Constitutional governance idea of EOS a failed idea. But make no mistake. This won't be a failure - this will be a rebellion, a coup, a removal of governance.
The question is why. So far ECAF has done no ruling that hurts any BP. Why do they want it gone? Couple that with all the other things going on in EOS and it is somewhat clear that the BPs are acting as humans. They want no other power but their own. BPs want to rule EOS.
But, is that a good thing?
