I can't be sure, but my interpretation of the parent's comment is that the USB-IF would never have thought to work on USB-C at all until Lightning's release two years earlier. The whole forehead-slapping moment of cables that didn't need to be flipped was a pretty big divergence from the USB-A, -B, mini B, micro B, etc. that has prevailed previously. The kernel of the argument being, Apple's "innovation" by rejecting the status quo is what allowed for the (eventual) development of the USB-C standard.
This is actually fairly common in Apple-land, now that I look:
- ADB (1986) to PS2 (1987) to USB-A (1996) for HID
- Firewire (1995) to USB 2.0 (2000) to Firewire 800 (2002) to USB 3.0 (2008) for data transfer
- VGA (1987) to ADC (1998) to DVI (1999) for video
A lot of the connectors they proposed are now lost to the mists of time, but I can at least understand the argument that some of these changes were plausibly driven by Apple's rejection of the then-standard in favor of some new benefit (faster speeds, better UX), which lasted only until a new standard was developed to incorporate that benefit, and the process repeats again.
