Earlier quoted context omitted.
If a stock trading app manipulates the market by preventing purchases, while allowing selling, of certain stocks that are popular with a democratized hedge fund community, they deserve all the 1 star reviews they get. It's not just an useless app now, it's an actively dangerous scam app.
It already was a dangerous scam app. The data on trades went straight to front running traders, so they could feed their algorithms and profit off your plans.
I mean, that's what you get for not paying for a service. It's a trade-off people knowingly took.
