I think you'll find they already did this last year - maybe not with common share positions, but they were certainly yolo-ing on weeklies, which was forcing delta-hedging, and the stock up. Looking at WSB now, it's all GME and BB discussions/memes, last year for along time it was TSLA, for months, and lots of references to "papa Musk"
Although they probably don't have the capital to shift the stock the way they did with GME, I'm pretty sure they helped
Although I'm cheering them on - I do wonder why the SEC isn't looking into their activities, it's clearly coordinated stock manipulation, and in broad daylight too, but more power to them - the more shorts get burned, the better
