It's all over the news. You don't think a story where a company halts buys so an investor can recoup their loss at the expense of the retail investors won't affect faith in the market?
Will it impact faith in the market? No. It will absolutely cause people to think twice about Robinhood as a brokerage, but that is a small portion of the market.
I was able to trade GME all day on E Trade without a single issue.
