But this does not mean that the Facebook will fail in its current use case. You are most likely currently using an IBM-compatible PC running Microsoft Windows on which you run Google for searches and Facebook to reach friends. There are some losers in those stories and they are losing to direct competition: IBM is losing on profits because they made their system open and anyone can build IBM compatible PCs, Microsoft is losing because people were for some strange reason ok with Apple creating a closed operating system (iOS) where they take 30% of any transaction that runs on it. Microsoft are trying to change this with Windows 10 and UWP, but hopefully it will fail just like Bing.
