Yeesh. This whole thing sounds like some gross commercialization of a problem blown out of proportion, that doesn’t really work, hurts honest customers, and only gets enforced due to some sunk cost fallacy going on in the minds of the venues/entertainers that were duped into using this “product” by the IP attorneys that are throwing bad ideas out there to justify the size of their salaries. I have no doubt the same sort of thing is going on with the linked article, only it’s a different branch of the legal team involved this time.
