I think the times have changed, and methods of survival changes also. We can compare previous behemoths, and their lack of actionable strategy to survive, with current times. I think we are entering much more violent times, where huge corporations will see a crashing end. If there will be great, easy to use, easy for user alternative to Facebook, that will be able to fill all the blanks quickly, would Facebook's value, stock and revenue withstand for example 250 Million user drop? Those would be the users that are unlikely to come back, and this would initiate huge migration. There is a time when a company screws one time too many, disruptor shows up at the right time with the right cards in its hand and literally syphon the value out of the big company. This happened many times before. See how Google showed up with better solution, very adaptive strategy and no annoying noise and rip apart the whole search engine niche.
