Third: Free software Organization Agreement:

1:gfdl:gnu the short form of the Free Document license (GNU documentation License).

The freedom here is not price free, it's not about the price but the use of software is free for all users. The GPL achieves this through the following means:

1). It requires that the software be published as source code and that any user can copy or publish the software to other users in the form of source code.

2). If the user's software is part of any software protected by the GPL, the software inherits the GPL software and becomes the GPL software, which means that the source code must be published with the application.

3). The GPL does not exclude the commercial packaging and distribution of free software, nor does it restrict the packaging and distribution of other non-free software on the basis of free software.
