Saying that GamerGate lacked leadership is wrong. It had multiple important figureheads that directed the movement over time, starting with Eron who turned a personal affair into an open-internet vendetta under the guise of 'ethics in video games' (of which the reviews and corruption people claim simply does not exist).

It blew up from there as many people became leaders of multiple subsections of GamerGate, many of whom we see today in the alt-right parts of the internet which I am sure is entirely coincidental. The difference between Occupy Wall Street and GamerGate is that GamerGate rallied behind multiple different leaders which would push the the movement towards various directions. This was all stuff I saw from personal experience.
