I like that Jane Street hires smart people and supports cool initiatives like ocaml.
But don’t fool yourself, they don’t make their money with intelligence.
They just do fees and insider trading.

If you really dive into the mathematics of finance, you quickly realize that the edge is never "we're better at math than you", but a much more fundamental asymmetry in information/control.
Sometimes that's getting information a few seconds faster, sometimes a data source no one else has exploited, but more often than not its something that feels a bit more "unfair".
Company X sued by company Y shouldn't automatically translate to company X did a bad thing. Companies get sued all the time.
Very wrong. Arbitrage is not “insider trading”.
They're accused of opening short positions, then pumping and dumping to trigger the shorts. That's not arbitrage.
What? “Opening short positions then pumping and dumping to trigger the shorts” doesn’t make any sense at all. You’re saying they opened a position that profited if the price went down then they bought to raise the price

By "pumping and dumping" do you mean "buying and selling" to outsmart other people trying to outsmart them?
Did they lie about the financial health of the securities they traded?
