Here's my take, they aren't simply attention whores. They're going to try and twist this into an opportunity to pass some shit like what Warren proposed under the guise of helping the plebs. What it'll actually do since it'll be a bill with a wordcount higher than War & Peace will probably in turn, keep this from happening again since it hurts potential campaign financiers and also get them brownie points with wallstreet, probably some horrific shit like a middle-class tax hike or a carbon tax, and possibly with some reform for 230 (to sink the ability to collaborate like this in the future) and/or finance law around brokers and such being able to legally pull the same shit Robinhood did earlier with selling stocks without permission for the "benefit" of the people holding them.
Never let a good crisis go to waste, indeed. The problem I see with them trying this horseshit is that this has become too big of a deal to ignore, and the narrative (for fucking once, finally) cannot outpace the truth due to the absurdity of it revolving around fucking gamestop of all things. I fully expect riots or some form of domestic upheaval if they go this route, ditto for the entities involved in this chicanery if they take this too far.
