Are you claiming there is such code? It would be a bizarre and pointless thing to add. Edit: To be clear, we are talking about different things. I assumed you meant placing a licensing requirement of only 5 users, which would not be possible for the reasons I explained. You appear to be talking about putting a restriction into the code, which as you say would not be prohibited by the GPL, but which would be entirely pointless for obvious reasons. It's an interpretation of their pricing plan that I hadn't considered, though, and I'm curious if that's what they're doing.
