This almost sounds like a plot for a novel. Microsoft creates a successful strategy called "Embrace, Extend, Extinguish" and then promptly forgets it, resulting in a string of failures. Google, which up to now seemed happy to repeat Microsoft's mistakes, accidentally picks up a successful Microsoft practice and uses it against Apple -- likely taking out a number of its Android partners. When Microsoft was starting out, its most powerful platform wasn't Windows, which was almost an industry joke at the time -- it was Microsoft Office.
