While there are many reasons to fill a class action lawsuit against corporations like Google for their abuse of monopoly, vague enforcement of "Community guidelines", opaque moderation decisions and so on, when it comes to Strategy, there are no legal grounds that I can think of to sue Michael Saylor for running a Bitcoin treasury company while not expecting volatility. Saylor has been repeating a million times that they work with volatility, and the people that are filling the lawsuit did probably unfortunately buy at the very top of the speculative mania where the options market had created a gamma squeeze. Those people are the same ones that bought Bitcoin at the top of a bubble, held all the way down and eventually capitulated locking in losses, then became Bitcoin haters, only to see Bitcoin 10x+ from there. Some people just cannot deal with volatility which is a must in Bitcoin and specially Strategy.
