As has been explained in multiple other places, the limitations were as a result of Robinhood et. al. being unable to cover the risks involved in providing instant trading capabilities for a stock as volatile as the ones that got restricted. That has nothing to do with "the little guy is winning" whatsoever, and in fact may indicate that "the little guy" is about to lose his shirt, due to lack of predictability.
Trading was not stopped "to save the hedge funds". This is an outright lie that needs to be squashed. Stop saying this. I don't mean to be rude, but the narrative you're spreading is actively dangerous and not supported by any of the facts we have available to us.
Yes RH had to cover more, because the clearinghouse was also starting to be stretched by the risk from the violatility. If the hedge funds go down, the clearinghouse wouldn't have been able to front their cash, and they would've gone down as well.
You're also missing the point that the clearinghouse firms didn't just ask for more money from brokers. In many cases they told brokers to step selling these securities.
There's increased risk on both sides, but the long side is at least finite (and probably there's not much margin). The short side is not. The unknown risk the clearinghouse needs to worry about is the short (hedge fund) side.
The claim that "the hedge funds" operate in unison and/or are all short is probably the largest misconception about this whole situation. Very "us vs. them" and also very wrong.
That to me looks like the clearing houses themselves are worried, which means the whole thing poses a risk (even if easily mitigated) to the greater market.

If crazy retail investors can bankrupt Robinhood or other over-leveraged brokerage firms, that's also a win for the little guys.
I don't think many HN posters with their stable, extremely well-paid technology careers can truly empathize with the strain of aggressive nihilism on display at WSB.
"I'm only gambling with my future, so nothing to lose."
Once one accepts that "socialized risk and private profits" isn't acceptable, then one must also accept that either we must allow even the too big to fail actors to fail, or we must not accept any actor to be too big to fail at all.
If public money is used to rescue a bank or clearinghouse, then the public should own it. A government institution can buy any failing bank/clearing house/ if it's so vital, and then the public owns it. Buying a commercial bank or clearing house at cents for the dollar and then selling it again in better times isn't necessarily a bad idea. It's certainly a better idea in terms of moral hazard than simply "bailing out" banks without ownership.
The fact that buying was limited yesterday is evidence that the little guy is actually winning here.
Trading was stopped to save the hedge funds, because if they go under or lose too much, the clearinghouse has to front that. If the clearinghouse goes under the whole market will crash.
