The link is now http://www.epsg.org/TermsOfUse but the content is the same.

This restriction seems similar to Apache 2.0 conditions, in my
understanding of the "May I call my modified code 'Apache'" entry in the
http://www.apache.org/foundation/license-faq.html#Name-changes FAQ. The
difference is that, as an extra flexibility, EPSG terms of use
authorizes the modified products to keep the "EPSG" name if the
modifications comply to their conditions.

We may amend the above proposal with the condition that, if the user
modify the database, he must change the EPSG name to something else.
