That's often not an unwelcome side-effect. If you're at a large technology company, making sure companies like yours don't use the free version is a common motivation. Aerospike sells a commercial enterprise license; in that kind of a "dual-license" setup, the GPL/AGPL can function as a useful poison pill to keep from cannibalizing enterprise sales with the free version (where a common alternative would be to just not open-source at all, for fear of that cannibalization).
