I'm not a lawyer and I've never played one on TV. 😜

I believe when the authors release the modified software to the public, which in the case of the Affero GPL means the software is providing service to the public, the source code for the updated software must also be shared back to the public (through the copyright holder?).

I'm not sure about the details of how authors keep or give copyright for their modifications to the copyright holder of the original project or not...

I think you're right that the copyright holder can change the license for future versions, but I don't think that any author can change the license, which I think is the protection provided.
