One might want to do this to keep others that might be using the studio from reconfiguring the FX Chains that they rely on.
What got me interested in this is that some of the FX Chains provided in Platinum don't allow you to easily see the underlying effects that are contained within them or edit the properties of the FX Chain to see how the UI is integrated to each of the underlying effects. (At least, I haven't been able to figure that out on some of the FX Chains provided with Platinum. Check out the "Acoustic Piezo" for an example.)
I'd like to know how to configure or protect my FX Chains similar to those FX Chains.
Thanks,
Paul
PS - I guess another reason could be that if you can protect an FX Chain from reverse engineering, then it would encourage enterprising knowledgeable people to produce FX Chains, with value to others, that could be sold.
