The one they used when they didn't make FaceTime an open standard from the get go. Clearly they knew they couldn't make it an open standard when they announced they intended to, but they still made the promise.
This isn't unique to Apple, but it's stupid to ignore reality. At the end of the day, they haven't release Swift. Banking on it now is, without a doubt, a foolish gamble.

And you can guarantee that Swift will be entirely open sourced? Sorry, but it doesn't change things because of reality. Apple hasn't released Swift yet as open source. So far, I'm winning.

Besides FaceTime? Off the top of my head, see the releases of the iPod, iPhone, and iPad. All were released with claims that were turned completely around (only for Mac, no native apps, smaller versions are bad). This ignores other things like how multitasking is bad one year and then good the next.
Simply put, when someone from Apple says they won't ever do something, I assume they just haven't come up with a way to market it effectively.
