I really dont think so and I also dont think that facebook is aiming at becoming an operating system. From my point of view, facebook is already way too much in peoples lives and has access to too much private data, this would only get worse with it becoming an OS. However this is the fault of the people themselves, they are exposing their private data to companies like facebook without thinking of the potential consequences. Im really happy with my life without any of those social media channels! (as you can hear, Im not a big fan of FB)
