I don't care about Apple, so I don't care about the ad. It lowers my (already pretty low) opinion of them, but that's about it. If this kind of thing was done by a company I'm a huge supporter of, sunk a lot of money into, one I personally promoted to my friends and family and one that was part of my personal and professional identity in some way, it might be very upsetting. I might feel betrayed. Personally I don't get invested in companies or products like that. Maybe you don't either. The emotional reaction makes sense if there's high emotional investment. Whether the emotional investment is rational is an entirely different question.
