We've had other threads on this. In a world that has increasingly embrased the "non-apology" (sorry that you were offended) I think it's kind of nice that people are at least accepting that it was their fault. If this expression gives them a painless way to do so, then it's not a bad thing.
I was living in Germany when this expression came into general use in the US. I was horrified the first time I heard it. It sounded ridiculous to me. Now that I've been back in the US for a year, I've had a chance to get used to it. So I'm no longer completelyhorrified when I hear it.
