I can't be like "Rust is a shit language" and then expect someone to write a treatise in response. It ain't never gonna happen.
Well fine, by the sounds of it, you're the sort of person who also makes those Rust threads unbearable by commenting despite having never worked with or near Rust but calling people names because they have experience and have formed opinions. Let's just put it this way, the way the HN commentary has come across right now is like a guy in a bar telling your about a horse you should place a bet on. That's the level we're at, and that's why I talk about the mass hysteria as the more relevant point, because your average Joe has no business reasoning about dynamics of stock prices of fairly illiquid crappy retail stocks.
It's true that it could legitimately be considered an exceptional situation requiring exceptional mesure.
But in that case the only way to do that while simultaneously respecting your obligations would have been a complete halt on that instrument.
So the market manipulation accusations seem legitimate.
There are lots of really good reasons why RH would want to try and get their clients' net positions flat. Since they are exposed to an aggregate risk that individual clients aren't exposed to - and obviously, those clients won't think about this, but they have operational risk that RH can't execute trades.
Trading securities and/or advocating for a free & fair market in which to trade those securities =/= literal violent insurrection.
