I would assume that Apple doesn't support QR codes because most consumers don't particularly have a use for them.
I see QR codes everywhere in NYC, but actually getting one onto my phone involves stopping, taking my phone out, spending 10-30 seconds with the QR code.
If your advertisement is capable of inducing me to do that much work, that's a pretty fantastic advertisement. However, despite the QR codes being damn near everywhere, I've still not bothered to scan one.

QR codes are, in my estimation, a fad.
