The "Copyright" tag has been deprecated for about 5 years. It was
poorly named initially and should have been named "License" from
the very start. rpm added "License" as a tag to fix this problem,
and made "Copyright" an alias for compatibility.
5 or so years of compatibility is quite a long time.
Think about it... Does this sound correct:
Copyright: Mike A Harris
Or does this sound correct:
The latter is claiming that the GPL (whatever that is in this
context) is the copyright owner. That doesn't make any sense.
If we assume "GPL" means "GNU General Public License" for this
example, what the above line is saying is that the actual GPL
license text is the copyright owner. The GPL document is a
license contract. The owner of the code is the copyright owner,
not the license, so the ancient rpm usage of "Copyright: <some
license name>" is semantically incorrect, and may have legal
consequences as well.
Nonetheless, rpm kept this compatibility around for a very very
long time. Thankfully it has finally removed it, and any remaining
broken rpms out there can and will be fixed finally. ;o)

"License:" has been around at least since Red Hat Linux 6.2, if not
way way earlier than that. There is no reason to not use the proper
tag nowadays. If someone wants to keep compatibility for rpm versions
that are that old to not have the "License" tag (which I think is
pretty rediculous), they can simply do:
%define ancient_OS 1
Another mechanism that can be used, is to make the specfile a
template instead, and preprocess it with autotools, m4, cpp,
perl, or something else, to plop in the right tag depending on
which version of rpm is being used.
The number of rpms out there that this affects in this nature
is likely to be incredibly low.
