We've just found a new dress to stuff Corporate Raiding into.

In the 1980's, when you weren't worrying about the someone accidentally starting WWIII, Japan completely unraveling the American Industrial Complex, Dungeons and Dragons turning your kids into satanists, marijuana turning your kids into crackheads (1980's meth epidemic) or treating your child's ADHD not being a sign of responsibility but declaring moral bankruptcy on your terrible parenting skills, you had to worry about your company's hard assets being worth more than your market cap, and a bunch of people staging a hostile takeover so they could sell your company for scrap to release that 'value' that is really your rainy day fund.

Maybe the money went out of being a patent troll, so they are trying a new model? Buy a once loved, but now defunct, product and try it on with everyone on their massive mailing list. Maybe enough suckers will pay to make it worthwhile?
