Well this myth will be perpetuated for as long as retailers like BestBuy make BANK on their inflated cable sales, it's seriously the item with the highest profit margin they carry, CABLES! And lots of em. If they didn't have THAT money, they and others probably would not survive. If they did not survive, uninformed consumers would begin to turn more to the internet to find all of their cables and BECOME more informed (most people just assume they need spendy cables), driving these over-glorified cables and their pushers down. Hopefully, some day.
Just to remind, buy cables here! here! here! here! and here!

And speaking of cables, Usb 3.0 is now showing up everywhere. Looks like lengths up to 15 feet are not a problem and the power spec is greater than Usb 2.0 How very EXCITING!
