I think "following the logic to its conclusion" is not logical. We have a line, and right at the boundary it may be a tiny bit fuzzy, but we do allow multiple versions. That doesn't always imply the newer reader thinks they can do it better. They could simply love the work and want to record it themselves.
Yes, Archive allows critical reviews. It's not the LV forum. And, by the way, LV doesn't allow the files to be hosted on Archive; Archive lets us host our files on their servers. Without them, we'd have to pay big bucks to host all these audiobooks elsewhere. So in their sandbox, we play by their rules. But on our forum, we play by ours.

Donald is welcome to post his YouTube and blog sites if he likes. But a direct link to an improved version of a project/reader he has just criticized? No.
EDIT TO ADD: P.S. I greatly dislike pre-casting of dramas, when the pre-casting is done via PM or off the forum. There is some volunteering for roles done in the planning thread, but that's open to everyone. It's un-LibriVoxy to tell someone they cannot read a certain role because they aren't good enough (either style, or voice match, or whatever).
