AGPL doesn't restrict use:
"You are not required to accept this License in order to receive or run a copy of the Program."
"You are not required to accept this License in order to receive or run a copy of the Program."
There exist obvious circumstances of the program's use with which the license doesn't concern itself, and does not speak to, and so in those circumstances the user is not required to enter into the license.
A redistributor must enter into the license because it's a derivative of the GPL, and so it has requirements related to distribution.
A user who runs the program in such a way that visitors communicate with it from remote stations obviously is required to enter into the license also and comply with its requirements.
The license is applied to programs for which this would be a typical use.
It's in a section whose purpose it is to make it clear that you don't have to accept the license just have a copy of the program, but that if you convey the program your implicitly accepting with the license, that license being the only basis for your permission to redistribute.
Only if the user modifies the program.
The remote network interaction provision of the AGPL is conditional.
That makes hardly any difference.
