Using Moodle: issued a DMCA takedown for using Moodle

A competitor has issued me with a DMCA takedown notice saying that by using the standard Moodle login page with no modifications, I have infringed his copyright.  He says my Moodle login page is too similar to his login page which he also asserts copyright over. His login page is a standard WordPress wp-admin page.  This can’t be right. Who owns Moodle? I would like to report his actions.
