Sure, if you run a server that's only running some unmodified AGPLv3 software then you don't have to share the source, although in that situation the user typically has access to the source through other channels anyway (the market for selling private AGPLv3 code is pretty much non existent, so the code is almost certainly from a public project). In the real world people typically want to use code as part of their own service/application which contains domain specific logic they wrote themselves. >You can perfectly well run an AGPL webserver and not be forced to put your operating system under AGPL. Because the GPLv3 and AGPLv3 (the licences are identical in this regard) have explicit sections excluding operating systems and system libraries from the terms of the licence.
