I don't see how this creates standing for end-users. AGPL expands the licensees' obligations, but only the copyright holder has standing to sue over violations of the license. This is analogous to a party that distributes GPL licensed software in binary form while refuses to fulfill their obligations under the license by providing code. https://www.gnu.org/licenses/gpl-faq.html#WhoHasThePower https://www.gnu.org/licenses/gpl-faq.html#WhoHasThePower
