There are also people pointing to Classic and Bitcoin Unlimited and claiming that those efforts are done by people with an intent to destroy bitcoin.

I believe the current stalemate and schism can be sufficiently explained without resorting to conspiracy theories, and I do believe that if someone has the intent to destroy bitcoin, they would install well-funded sock puppets at both sides of the schism.

I used to be an optimst, and I used to shake my head when seeing those conspiracy theories - but during the last few months I've been growing more and more pessimistic.
