Jailbreakers
It will be interesting to see how the jail breakers handle this. My opinion is that the core teams are ethical - they Jailbreak so that users can install non-approved apps, unlock the SIM from a carrier, and so on. The downside is that this allows app piracy.
If there's a way to provide JB without circumventing the lock I would expect them to do it.
Of course, there will be others who will attempt to break the lock, but time will tell how widely available that knowledge (and toolset) will become.
