From what you say, it sounds like you do like GPL, but don't like AGPL because of this "modification" issue.
If you *modify* a GPL program (not Affero, any version), you must offer all its users the source code of your modifications, so it's exactly the same on these grounds. How can you like GPL and dislike AGPL?
What *is* different is who is considered "user":
- For GPL, user means somebody who received the program (even in a binary) and is running it on a machine where this user has some kind of control
- For AGPL, user means anybody who is "using" the program in whatever mean (e.g. as a webservice), even if the person hasn't "received" anything.
Thus, on the matter of "who the user is" you can like one and dislike the other, but that's not what you wrote (it's actually what I did wrote in my original comment that has been FUDed)
