Childish and Petty
Typical of Steve Jobs, but I really expected better from Tim Cook....I'm disappointed.
I see this as a good thing, YouTube app is old and hasn't been updated in sometime. This will allow for Google to make a better iOS app than what was currently offered.
It's not childish and petty. They decided that they didn't need to pay to renew the license. Why pay to put something on the phone if people can just download it from the app store anyway? Smart business move IMHO.
