I am not sure about the validity of the case but it is no doubt that the chip manufacturing companies earned a lot of money from mining enthusiast so that the gaming population was not able to get hold of the graphic card and the demand was so high at one point in time that you need to book the product months before it reaches your hand and historically there was never a instance like that and it was a one time anomaly and that rush has gone down substantially and in a stock point of view their profit margin will go down but these lawsuits are meant to squeeze money by the law firms .
