"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.

This is GPL-incompatible, since it governs how much I may charge for
I'm not convinced that it's Free, since the usual "package with the
trivial program" work-around doesn't appear to apply.

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.

That's fine, I think.

I think this can be interpreted as "without warantee from EDG" --
