Various reasons:

First of all, as mentioned, it's not an error. It's not rpmbuild that
would reject such a spec file. It's just rpmlint that warns about it. And
rpmlint has not been in use so much years ago (and possibly has not been
used much during the Merge Review era either).

Further, for some of the packages, there is no such URL. No home page.
Not even a download directory. Example:
http://pkgs.fedoraproject.org/cgit/basesystem.git/plain/basesystem.spec

Finally, sometimes (not limited to a missing-URL-tag) it's because the
packaging guidelines are not enforced by automated processes. And where
the guidelines say SHOULD instead of MUST, some people take that as
NEEDNOT -> LESSWORK -> DONE.
