Pebble is definitely a success, OUYA is another success, the Neil Young endorsed Pono player and service seems to be well underway and looking like another success and of course, the LIFX wifi enabled multi light-bulb as well. When you run the numbers, the percentage of success for hardware projects is quite small. But as you point out, Kickstarter get their fees regardless of success or failure. I think Kickstarter does care, the problem is just a lot bigger than they currently know how to fairly solve.
