Yes, you're absolutely right. There is a similar "disclaimer" over at SHIELDS. The funny thing is that these Mopologists are so anal about fair use and copyright and following the rules when it applies to their own stuff, or when it supports their agenda. But, when it comes to critics, or the actual protocol governing use of verbatim texts, they think the rules can be bent.
And might I point out for probably the billionth time (because that stupid claim irritates me to no end) - this assertion of copyright is void and not valid under current copyright law. You cannot assign a copyright to a person or entity via a "click through" - it must be a signed writing. This has been pointed out to MADB, but they ignore it and proceed.
It appears this copyright claim relies on a generous dollop of ignorance in its target audience. In that, it is not unlike Mormon apologia in general. ;)
