I do hope corporations in general take a harder stance on this. From a society perspective people with inside knowledge fleecing randoms is not a win. We've got that somewhat under control on the stock exchange, but have this absurd situation where on prediction markets it is a free for all and everyone pretends this is fine.
I also think corporations should distance themselves from individuals willing to fleece randoms. Trading in general is very wild west survival of the fittest but active exploitation of insider knowledge speak of very poor morale character
