Gregory once told me that going to 2MB was impossible because it opened the network to the possibility of blocks that would take 10 min to validate. That really opened my eyes to the disingenuous communication methods he uses. He knew full well there was a way to mitigate that, and that pure competitive mining would negate it, but decided that treating someone like an idiot and dismissing them was the best way.
His communication and technical "impartiality" hasn't improved since... I really believe that he is the glue and the gasoline that has held Blockstream's intransigence together and propelled it this far down the rabbit hole of "we were right all along". Bitcoin is broken in their eyes, and they need to fix it, the possibility of getting filthy rich in the process is just icing on the cake.
