This nonsense goes on every year and these people just don't get Apple.
They are a company that resolves entirely around their culture and their ways of doing things. They even have their own internal university that teaches it to their managers. Apple makes a dozen or so acquisitions every year but they are almost always small companies whose cultures typically ends up being eliminated over time.
Buying a large company would make it impossible for this to happen and so I just don't see any of this happening. Not to mention the companies you listed there are completely ridiculous.
