AGPL is specifically for web services. For example, if Nextcloud were provided under the GPL, Amazon or the like could serve a modified version of Nextcloud without having to hand out their modifications. As far as the GPL is concerned, Amazon is the user and the software just happens to accept requests from the network.
With AGPL, those who use the software over the network are also deemed users and therefore have the right to access the source code.


















Nah, you can have a license that says you get a cupcake and another license that says you need to give up your first-born.
And then you can mush those licenses to say that you need to give up your first-born, but you get a cupcake in return.
Unless the specific license terms contradict, this is totally possible.
