They seem unclear on their own copying licence terms.  Some of the say
"public domain" which is great.  Others say "no commercial use" which
is not but the final message in the thread indicates this isn't the
actual case.

So the licence seems to be unrestricted use with acknowledgement,
which is fine for KDE.

I'd recommend writing to them (again) to clarify though and maybe
convince them to use the GPL directly, let me know if you want my help
on a good phrase to send them.

Yes, they still own the copyright.

I don't see a download link for anything there, what actually gets
included?  It seems reasonable to infer that the intent is public
domain with attribution but I would e-mail them to check.
