I hope they do abandon it, because I know I won't go anywhere near the source until they do.
The AGPL contains this little gem:
"if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software"
Anyone that accesses your website is entitled to the source code you are using.
