Thus, free software means that computer users have the freedom to cooperate with whom they choose, and to control the software they use. To summarize this into a remark distinguishing libre (freedom) software from gratis (zero price) software, the Free Software Foundation says: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in 'free speech', not as in 'free beer'".[22] See Gratis versus libre.
Foxit Reader is free for not just reading, but also creating PDFs and collaboration on the files (at least you can with the Windows version; Mac and Linux are more limited). Foxit's MobilePDF apps are on iOS, Android, and Windows Phone. What's more, they support a tech called ConnectedPDF so you can send PDF files and even update them after you send them (thanks be to the cloud).

A special issue arises when a license requires changing the name by which the program will be invoked from other programs. That effectively hampers you from releasing your changed version so that it can replace the original when invoked by those other programs. This sort of requirement is acceptable only if there's a suitable aliasing facility that allows you to specify the original program's name as an alias for the modified version.

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.

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.
