The AGPL was created by a company named Affero, Inc. It's not clear to me whether that company even exists anymore — various sources claim that their web site was affero.com or affero.org, but neither site seems to be actively used by the company anymore. So at least for the creators, the license does not seem to have been a rousing success, although that is of course completely anecdotal.
