I'd argue it is both. Apple isn't going to convince an industry to move to a closed standard, however they may accelerate the move to new open standards. For instance, moving away from floppy disks to compact disk media, and moving from serial/parallel/PS2 ports to USB.
Often these technologies are stuck until there is a first big adopter. Now Google, Apple Macs, and most of Android is behind USB-C for instance, there will be a lot more accessories that use it. Right now IMHO it is being held back mostly by cost - micro-usb and an A to micro-B cable are still the cheapest parts.
