Then it would have ended up like Gopher[1]. In 1993, the University of Minnesota announced that it would start to charge license fees to use its implementation of the Gopher server. By 2000, when the university GPLed it, it was too late.
That's a decent guess, but I think it's also possible it would've followed the path of one of the pre-web online services like AOL, Prodigy, CompuServe, or eWorld. Those systems are what happens when somebody owns the marketplace and you need to get permission to set up shop, which (if the WWW took off at all) would more or less have been the state of things while the patents lasted.
Come to think of it, that sounds a lot like the realm of the app store in some ways.
