In this article, it discusses the effect of day traders on the stock market, including the recent GameStop fun:

One interesting note:
In the old days, retail investors were as a rule always the ones being outsmarted by hedge funds. Now the tables are turned.
It probably won’t surprise you that NASDAQ is going to make sure the little guy can’t do that again:
Remember folks, only the elite are allowed to game the system.
UPDATE: Tucker Carlson chimes in (sorry if a painful ad plays first):
And, as Tucker notes, Discord shut an associated trader community down:

Discord says it did not ban the server for financial fraud — rather, it was banned because it continued to allow “hateful and discriminatory content after repeated warnings.”
But, someone associated with the banned server pointed out:
We’re suffering from success and our Discord was the first casualty. You know as well as I do that if you gather 250k people in one spot someone is going to say something that makes you look bad. That room was golden and the people that run it are awesome. We blocked all bad words with a bot, which should be enough, but apparently if someone can say a bad word with weird unicode icelandic characters and someone can screenshot it you don’t get to hang out with your friends anymore. Discord did us dirty and I am not impressed with them destroying our community instead of stepping in with the wrench we may have needed to fix things, especially after we got over 1,000 server boosts. That is pretty unethical.
Update January 28, 2021:
More articles (first one comes with a curse word warning)…

Here is Robinhood’s CEO’s explanation:
To be honest, it didn’t seem an explanation beyond claiming they needed to do it and nobody made them.
Either @RobinhoodApp allows free trading like they say they do or they die. It’s really that simple. #ddtg pic.twitter.com/ZHfTjLxV5h

Gotta admit it’s really something to see Wall Streeters with a long history of treating our economy as a casino complain about a message board of posters also treating the market as a casino

Pretty sure only trained hedge fund professionals backed by institutional investors and UHNWs are supposed to commit theft/financial pillage by artificially distorting the market. I don't know why retail investors think they have the right or expertise to manipulate price action.

What kind of soulless human being do you have to be to short brick and mortar businesses during a pandemic? When these companies are not even allowed to legally operate. These suits have no solidarity, they care nothing about America. I’m glad Wall Street Bets is punching back.

Robinhood was never what it pretended to be. It built its business on selling Wall Street Bets order flow to the hedge fund Citadel. In the moment of truth, we learned which customer it cares about the most.
