iLok has been extremely effective at stopping cracks or at least slowing them down enough to where the software is obsolete by the time a crack appears. The pirates don't have access to this software in the first place.
We can debate the merits of DRM all we want, but PACE's stuff actually works (at stopping pirates, and sometimes paying users)
Not only that, if you want to sell and transfer your iLok license you have to pay $20.
I will never buy anything that requires iLok.
