Sorry to learn of that misconfiguration in your IT system.

It is true that all of the different licenses, granted in the many different packages, have an explicit freedom in common: The freedom to redistribute the work you received, with or without modification, under the same license conditions as you received it. There are other conditions and grants in various packages, but that common grant of freedom is the one I think you are referring to. > But whether we need open source our test software.I did not find the > relevant instructions on the official website. The instructions are not special to Debian. If you want to redistribute a work derived from another work, that action is goverend by copyright law and you must obtain permission somehow. For free-software works, like all the ones that comprise the Debian system, the freedom is explicitly granted to redistribute the derived work with the same license conditions that you received the work. > We do not want to open source our software, because it will involve the > interests of some third-party vendors. That is a shame, because it is against the interests of software freedom and the interests of software users. Please grant recipients of the Debian system – with or without your modifications – the same grant of license that you received. -- \ “It is seldom that liberty of any kind is lost all at once.” | `\ —David Hume | _o__) | Ben Finney
