I'm a new user of nebula 3 pro. Bought some Alex B libraries too . If they step up the CP on Nebula I believe this has to go hand in hand with usability and quality. I love this plugin but it feels a little like (Oh I hope it works today properly).
As regards to pirating in studios I don't have much knowledge of this (as I'm not a professional). Though in the gaming market people pirate all the time even when owning a copy of the license to avoid CP inconveniences. Maybe the same goes with pirating plugins? I have heard also that of people pirating to evaluate software in a kind of glorified demo perspective, before purchasing a full license (some demo limitations can effect this?).
Anyways as long as the software is good well priced and easy to keep updated/re-installed then I think CP is a good idea.
BTW I'm glad to being a new member of this interesting community and hope to contribute in some way one day.
