Microsoft CEO Steve Ballmer stated in 2001 that "open source is not available to commercial companies. The way the license is written, if you use any open-source software, you have to make the rest of your software open source." This misunderstanding is based on a requirement of copyleft licenses (like the GPL) that if one distributes modified versions of software, they must release the source and use the same license. This requirement does not extend to other software from the same developer. The claim of incompatibility between commercial companies and Free Software is also a misunderstanding. There are several large companies, e.g. Red Hat and IBM, which do substantial commercial business in the development of Free Software.
One of the new class of messaging services with an ecosystems of apps, Telegram delivers not only easy communications, but also encryption security end-to-end. It's a stand-out on iPhone, and has native apps on just about every platform available. Send messages, files, photos, animated GIFs (the search is built in), and create channels of up to 5,000 people to broadcast to.
If you don't know or care what a media server is—you just want to stream your videos and music collection around the house—Plex is probably for you. Install it on all your devices, point it at some media, and the media is available on all of them—even remotely over the internet. Plex plans to implement a cloud-based server option on Dropbox, Google Drive, and OneDrive, so you can stream from the Web.
The FSF list is not prescriptive: free licenses can exist that the FSF has not heard about, or considered important enough to write about. So it's possible for a license to be free and not in the FSF list. The OSI list only lists licenses that have been submitted, considered and approved. All open-source licenses must meet the Open Source Definition in order to be officially recognized as open source software. Free software on the other hand is a more informal classification that does not rely on official recognition. Nevertheless, software licensed under licenses that do not meet the Free Software Definition cannot rightly be considered free software.
This last point, which allows the software to be sold for money seems to go against the whole idea of free software. It is actually one of its strengths. Since the license allows free redistribution, once one person gets a copy they can distribute it themselves. They can even try to sell it. In practice, it costs essentially no money to make electronic copies of software. Supply and demand will keep the cost down. If it is convenient for a large piece of software or an aggregate of software to be distributed by some media, such as CD, the vendor is free to charge what they like. If the profit margin is too high, however, new vendors will enter the market and competition will drive the price down. As a result, you can buy a Debian release on several CDs for just a few USD.
