The FSF argues that free software should not place restrictions on commercial use. This forbids activities such as distributing of the software under a non- disclosure agreement or contract. The fourth section for version 2 of the license and the seventh section of version 3 require that programs distributed as pre- compiled binaries be accompanied by a copy of the source code, a written offer to distribute the source code via the same mechanism as the pre- compiled binary, or the written offer to obtain the source code that the user got when they received the pre- compiled binary under the GPL.
