Dirty way to make money: Warren Buffett's partner on Robinhood's trades

Charlie Munger, Warren Buffett's business partner, on Wednesday criticised Robinhood and other brokerage apps for enabling the recent trading frenzy in stocks, including GameStop. He said these brokerages that attract amateur investors are essentially selling gambling services to them and "it's a dirty way to make money". "Nobody should believe that Robinhood's trades are free," he added.
