Vindictive it might be, but childish it is not. I really think Apple has to get away from the dependency on Samsung; it needs to partner with a company that doesn't have the potential of taking advantage of Apple's product roadmap.

I cannot believe that people don't talk between Samsung's mobile division and their semi-conductor fabrication business (regardless of NDAs). I think being Apple's supplier and themselves being in the business of making phones and tablets, has worked to Samsung's advantage.

That being said, I think Samsung is a really powerful company and they'll be able to hold their own (i.e. revenues from product sales etc.) without Apple's business.
