This is not a revelation at this point in time, especially to those who have been following the progress of open-source, or have been studying its economic advantages to proprietary software. Our societies have been moving towards open-source for a long time now, to the point where it is not a matter of opinion, it is simply a fact.
Out of all the open-source code there is out there, the one that is expanding the most is Linux, a free as in freedom kernel, which is being used on multiple OS’s in all areas of computing. The most common of which are Ubuntu, Red Hat, Cent OS, and Debian. All these have their specific areas in the economy. Ubuntu does a great job at providing an alternative to Windows and Apple on PC’s, while Debian is mainly used as either a PC OS for programmers, or a server OS, seeing that the Debian community has a version of Debian for servers. Red Hat and Cent OS are often used for super-computers and clusters. Finally, the newest member to the big league Linux OS’s is Android, which has dominated the mobile and tablet markets.
Again, this is not a matter of opinion, these are facts. In the following link, you can see how Android is dominating the mobile market. If you look at the following Wikipedia article (yes, I know Wikipedia isn’t meant to be a valid source, but you can look up the information yourself and you’ll find about the same thing), it shows how Linux has dominated the mobile market, the server market, it’s rising in the tablet market, and it has taken over the supercomputer market (the supercomputer market is no surprise though).
However, open-source is also dominating the gaming mark. The new PlayStation 4 that has recently come out is using FreeBSD underneath as an OS. Recently Steam (a game distribution platform owned by the Valve corporation) is creating their new SteamOS which is based on Debian GNU/Linux, therefore, it must be open-source by law.
However, the reason why Linux and open-source are becoming such an important part of the technological world, is because they allow flexibility and stability. Flexibility because it allows, not only companies and governments, but also every day people, to change the source-code to their own needs, apart from knowing exactly what is in there. This is why the U.S. military uses Linux (specifically Red Hat, which is U.S. owned), because they can modify it and change it to their needs, and know exactly what is in there. So the flexibility makes it very attractive to companies, governments, and individuals alike. And Stability because open-source will always be open-source (especially if it is under a GNU Public License). Even if Linus Torvalds (the creator of the Linux kernel) decided to close the source-code to his kernel, all the people that previously worked on the Linux kernel would then just use the previous source-code and create a new kernel based on Linux, and there will always be an open-source kernel, and there will always be an open-source OS. And because it is open-source, for the most part it is also free. Therefore, companies, governments, organizations, communities, and individuals alike, have a guarantee for life that they will always have a free, and free as in freedom OS.
