(therefore a derived work)

The wording in that file is not a request, rather, it's quite
compulsory. Can you please find a statement saying this *is* a request
from the author and not a requirement (it reads as a requirement to me)

Again, this wording is not a request. I get the impression terms may
have changed at some point, as I've pointed out.

If it's copied the code, it's subject to the same terms. Again, it's not
a request as worded above.

Again, this does not read as a request.
