I agree with everything you've said here, but their strategy seems to be that as long as everything is kept arguable ("plausible deniabilty"), they will always win the argument ("Might is right").

You, and actually anyone, is invited to comment on it, and / or take from it whatever you / they like.
It has been thoroughly scrutinised by Ai and appears to withstand all criticism so far, eliciting many poems by it.
I hope it helps.
