If the purported collaboration between Blockstream and Bitcoin Core is so powerful – establishing "monopoly" status, and serving as a so-called "politburo" – why have they not activated SegWit? Wouldn't a small group of monopolists surely possess and use such power to activate the single most important feature to the Core community?
This is a very simple question Bitcoin Unlimited supporters have failed to respond to – in several different forums. They should be pressed on this issue, because it is among the (if not THE) biggest contradiction / fallacy they face.
If Bitcoin Unlimited is going to continue to base the majority of its blatantly false propaganda around this idea, then the question should be asked repeatedly, and often: if Core is so powerful, why has it not activated SegWit?
