(A)GPL + Dual licensing is totally insufficient to fullfill the needs, or at the very least the wants, of people using things like "Fair source" licenses (regardless of the naming): to share their code as a sign of goodwill, without that becoming a risk for their survival.
Amazon offers lots of AGPL software, and they fully respect the license in all cases. Ultimately the GPL is about protecting users' rights at the expense of developers' rights. So as long as AWS can offer a better/cheaper managed version of a software service, while still giving the users all details on how to run the same service if they chose to, then the AGPL is completely achieving its aims, even if the original company goes out of business.
