I think it's because they jump on that bandwagon so quickly...kinda like everyone else.What is the big deal? Whatever they are selling belongs to them up until somebody buys it. As it belongs to them they can sell it for whatever they decide it is worth. It is not gouging, theft, or any other kind of larceny.
If you don't want to buy it, can't afford to buy it, or think it is a ridiculous price go somewhere else for it.
Obviously some are willing to pay the price or the company would be having trouble staying in business.
