"at no charge" is ambiguous -- do they mean that they grant this license at no charge to me, the distributor? Or do they mean that I must not charge those to whom I distribute? Given the following, it looks like it requires me not to charge for Elm. > with any other product for sale, provided that the cost of the > bundled package is the same regardless of whether Elm is included, > and provided that those interested only in Elm must be notified > that it is a product freely available from the Elm Development > Group. This is GPL-incompatible, since it governs how much I may charge for Elm. I'm not convinced that it's Free, since the usual "package with the trivial program" work-around doesn't appear to apply. > 2.

I have to continue to maintain a source archive and provide it on request -- even if I originally provided source? I'm not convinced that this is free. > 4.
