Just notice that it is always the ones going for IPO that talk like this. Microsoft/Apple/Google, they don't talk like this because they don't need to, they are already certain of their positions (for the most part).

What I mean is, how many projects, services and features have been scrapped in Microsoft, Google, Apple that we never knew about. It would have been weird if Tim Cook came out and said "We had this great new feature for the iPhone, but we aren't doing it now. So yeah, yay us!"
