If you are buying GME at this point after the publicity, you know absolutely that it’s gambling. It’s had 50+% swings every day for the last week or so.
Even on WSB the posts are very much about it being a batte that has a potential of being lost. There is no pretense of GME being an investment that only goes up or that GME is some up and coming company.
But there's about 5 million new people subscribed to that sub in the last couple weeks, and I don't believe they all know holding GME is gambling.
