I sympathize with your confusion. There is inherent confusion around the
differences between "sharing" and "free/open source." In the former case,
it's just something people do. In the latter case, it is a legal standard.
Livecode Community uses the GPL http://www.gnu.org/licenses/gpl-3.0.en.html
This is important primarily because your standalones include the Livecode
engine. Livecode owns the copyright on the engine because their programmers
wrote it and assigned their copyright to the corporation. Leaving it at
that means that nobody else has any right to anything with regards to the
Livecode engine. In order to facilitate things like community, and
learning, and customer development, Livecode is giving you (us) a license
to use the engine provided certain conditions are followed. In this case,
the GPL is a viral license in that you are only given a license to use the
code if the binary you produce with it also uses the GPL (or compatible)
license. Those are the terms under which Livecode is comfortable allowing
you to use their intellectual property.
It's worth mentioning that the language itself doesn't work the same way.
If you open up a text editor, and write down words which the Livecode
engine might happen to understand, then you still own the full copyright on
those words. You can do anything you want with them. So the copyright on
the source of a script-only stack belongs to you. If you compile it into
the standalone then it must be licensed GPL.
That means there's a gray area around something like distributing a
Livecode-compiled binary under the GPL (source must be provided) and also
providing one or more encrypted scripts which that application can decrypt
and access if it needs to. As I understand it, the GPL blocks distribution
of a GPL-licensed executable that *requires* closed-source libraries to
run, but does allow the copyright holder to write in a specific exception
if they want to. The gray area refers to an optional library that *enhances*
(like a plug-in) the GPL-licensed application. I think that is merely
discouraged, but not actually blocked.
So it might be worth asking Livecode if they'd be willing to add an
exception to their GPL license allowing "hobbyists" to distribute a
closed-source library that is not compiled into the GPL-licensed
standalone. That would allow "hobbyists" to keep some of their code secret.
Maybe Livecode could even charge a different amount for that license.
