The amateur radio community is not universal in their dislike for this rule. I don't personally see any way in which the rule could be removed without altering the fundamental character of the amateur radio service.

You simply should not be making transmissions in the amateur radio service that require privacy. Permitting unrestricted encryption makes that basically impossible to enforce.
