Public domain software: the copyright has expired, the work was not copyrighted (released without copyright notice before 1988), or the author has released the software onto the public domain with a waiver statement (in countries where this is possible). Since public-domain software lacks copyright protection, it may be freely incorporated into any work, whether proprietary or free. The FSF recommends the CC0 public domain dedication for this purpose.
There are thousands of free applications and many operating systems available on the Internet. Users can easily download and install those applications via a package manager that comes included with most Linux distributions. The Free Software Directory maintains a large database of free software packages. Some of the best-known examples include the Linux kernel, the BSD and Linux operating systems, the GNU Compiler Collection and C library; the MySQL relational database; the Apache web server; and the Sendmail mail transport agent. Other influential examples include the Emacs text editor; the GIMP raster drawing and image editor; the X Window System graphical-display system; the LibreOffice office suite; and the TeX and LaTeX typesetting systems.

We are back again, this time testing... Apple’s Mac OS X. [...] While the results were reasonable, we were disappointed to find that the reliability was no better than that of the Linux/GNU tools tested in 1995. We were less sure what to expect when testing the GUI- based applications; the results turned out worse than we expected.
In this program governments and intergovernmental organisations pay substantial fees for a superficial look at some parts of Windows sourcecode in special Microsoft facilities. This may increase "perceived security" but is essentially useless - especially since they do not even know whether what they looked at is what they have on their computers. And of course it does not give them freedom.

At first glance, this looks like Dropbox or OneDrive, but Resilio Sync (formerly BitTorrent Sync) skips one aspect—it syncs file between computers without the files ever hitting a server on the Internet for online storage. This is purely peer-to-peer syncing, and works great with large files. For free, you get syncing between two devices but with unlimited data.
These freedoms are rights, not obligations, although respecting these freedoms for society may at times oblige the individual. Any person can choose to not make use of them, but may also choose to make use of all of them. In particular, it should be understood that Free Software does not exclude commercial use. If a program fails to allow commercial use and commercial distribution, it is not Free Software. Indeed a growing number of companies base their business model completely or at least partially on Free Software, including some of the largest proprietary software vendors. Free Software makes it legal to provide help and assistance, it does not make it mandatory.

In addition OSS’s development process is creating innovative products that are reliable, secure, practical and have high usability and performance ratings. Users are now not only benefiting from the OSS revolution but also from the improved proprietary software development that is being forced upon suppliers in order to maintain competitive advantage.
