Apple, Google, Microsoft, constantly buy, "sponsor" or sue competitors (whatever is cheapest) in order to keep their monopoly. All innovation is killed or at best assimilated (Star Trek Borg style). It's a bit funny that we ended up with two major platforms for smartphones... Microsoft did have a good grip on the smartphone market before Apple and Google entered, but they couldn't simply buy Apple or Google in order to keep their monopoly, nor can Google buy Apple or vice versa. But they can kill anyone else that tries to innovate.
