The "stock-agnostic way" metric is volatility. GME experienced volatility never seen before. Thus measures never taken before are justified. Given your quotes around "had to" I suspect you don't believe Robinhood was essentially forced into these measures. If you're going to hate Robinhood, it should be because they created a gamified app that emboldened people to jump into the GME debacle and for creating a service that goes down in times of heavy trading, not because they had to take measures to reduce their risk profile.
