They weren't delivering power over Thunderbolt (though technically possible I think). By moving to USB-C they are now on tech the rest of the world is likely to pickup. It's also pretty likely that it's more power-efficient than Thunderbolt and less complicated. (The Intel Thunderbolt controller is a mean looking IC that gets pretty hot)
