I dont think he blamed them for causing the problem, I think he blames them for not having the balls to stand up to Blockstream and force the issue by adopting bigger blocks.  As he explained, it was down to this funny sense of 'loyalty' - which is commendable in principle but should never stop you from doing the right thing.

But I see why the miners did what they did - the "pig circus" that was 'Scaling Bitcoin' promised that something was going to be done, but instead became a simple delay tactic while convoluted, unworkable solutions were being hammered out in the background.

But time has now run out, as it has for XT, and miners are now taking a pro active stance on the matter. All they are waiting for is somebody credible to put an alternative solution in front of them - a solution tailored to their needs - and they will jump.  And that will be sooner than many here care to believe, and certainly too soon for alternative vaporware to become a reality.
