Because Amazon has allowed their store to be filled with buyer-beware scams. Much of their electronics are knockoffs - good luck buying legit batteries, chargers, etc. You're shopping, with inventory commingling, from who knows who. Is the device actually new, or is it a refurb or return? Etc. For any substantially expensive device, they can also void the warranty by not being an authorized dealer. Or at least create a hassle for the person attempting to use that warranty.
