Quitting from a social media/public forums because people promote themselves through large stakeholders based on a overwhelming demand for those promotional services is still a very poor reason to quit. In the real world centralization of power happens by the hand of those bosses. Here centralization of power is insignificant to people that are like me, who will speak and upvote regardless of how many flags or how much resistance there is because to me centralization of power in that respect doesn't affect me in the way that actual centralization of power would. I hoe that those that left did so because they considered the alternatives (none) and decided that they are better, but that's not likely, they probably went back to the mindless facebook newsfeed.
