Hello list,

It’s important to remember that open-source is different than free, which is different than copy-left.

The two most prominent early examples of open-source software (Smalltalk and UNIX) were both very much copyrighted commercial products of large companies.

By the same token, there are many free software applications these days that are closed-source, distributed as compiled binaries.

The copy-left made (in-) famous by the GNU project says, “by incorporating this software into your own (or even using these tools [e.g., gcc] to develop your software), you are required to make your software free and open-source.

Either way, end-user licenses are free to stipulate any conditions on the use of the software that the developer wishes, such as, “By using this software, the end-user commits to name their first-born child Moonbeam,” or, as in the case of both JUCE and Visualworks, “free for non-commercial use only.”
