It was all initiated on a sub-group of Reddit known for its heterodox interest in stock markets, video games, and vaguely populist politics. 

Purposely targeting the stock of a company that had long been written off by Wall Street and which short sellers had decided to ravage — the video game retailer GameStop — these small investors, many apparently working class or debt-ridden, banded together to drive up the stock price of that company into the stratosphere, abruptly leaving the hedge fund short-sellers with billions of dollars in losses.

Although it may be more complex than this once all the facts are all known, this is being treated — by those excited by it and those aghast — as a type of populist uprising, a David v. Goliath tale in which ordinary people united to brilliantly beat Wall Street at its own game, thereby transferring plutocratic wealth back to the public. Oligarchs and their media spokespeople spent all day on CNBC and other pro-Wall-Street outlets expressing outrage and demanding government intervention to protect them from what they regard as this grave injustice.

And the sub-Reddit has now been banned by at least one platform, on the highly suspicious ground that it was due to "hate speech" and not the use of this group to sabotage Wall Street billionaires (what a remarkable coincidence of timing that this sub-Reddit's "hate speech" suddenly crossed a line exactly as hedge fund managers were demanding their heads; the page continues, however, to appear on Reddit itself).
