Apple has a very closed ecosystem and at least some think the company may be headed down the road of antitrust litigation if it isn't careful. This article asserts the problem Apple could get into is an area where Google absolutely dominates - advertising. To me, Google will act as an eternal counterbalance letting Apple get away with a great deal as it fights the search giant.
This by the way, this is why regulators allow Oracle to buy anything and everything... The argument is we need this stuff to compete with Microsoft. In some ways Apple is double protected as it will argue it needs to pursue its business goals in an effort to balance out both Microsoft and Google. And in many ways they will likely be right.
Do you agree?
