To be really fair, they're being sued by lawyers hoping to take 50% of the proceeds, or 50% of some settlement that they get by shaking down Costco via threats to its reputation.
Adding "bullshit" to a sentence does nothing to hide this kind of ambulence-chasing vulturism and exploitation - in fact it rather highlights it.
I mean, one of the legal firms behind this is Milberg PLLC, https://en.wikipedia.org/wiki/Milberg, who has been charged with illegally paying plaintiffs to sue in order to enrich themselves.
Is that the case history? Or bullshit assumption? Because this looks plaintiff sponsored.
