acousticsamples
We don't use NI service center because... well... it is provided by NI and requires to use Kontakt and their inefficient protection.
One of the most feared situation of sample libraries developers is to release a Kontakt powered library and see it the next day on top of the pirated library list...
Well just be careful you don't start walking down the road of caring more about piracy than you do about sales. Remember that piracy, in and of itself, doesn't matter, at all. What matters is sales, and more to the point profit. Piracy only matters if it is translating in to lower profit. If piracy doesn't affect sales, because the pirates aren't people who would buy, or increases sales (not that is likely, but just saying) then it isn't a problem.
More than that, if you use a DRM method that is disliked, like the iLok, you have to consider all the costs. There is the direct cost of licensing the technology. It is not trivial, as you well know. So it has to at a minimum increase revenue by enough to cover all those costs or it is losing you money. However there's also support costs. The more intense the DRM, the more users that will have problems and thus the more you spend on support. Harder to measure, but equally important. Then of course there's the lost sales. Some people will just not buy things with intense DRM, and we don't lack for good options of samples these days. So you need to consider that as well.
Now maybe you guys have run a good actuarial analysis of all this and determined you make more money. However to me, it sounds more like you've done what many devs did: Got mad that your stuff is on torrents and decided that piracy has to stop, without doing a cost/benefit analysis.
I mean let's look at NI: They have this very weak protection, yet they are the dominant force in sampling. They sell their stuff left right and center; they managed to sell out of their Komplete and Komplete Ultimate bundles and are a number of weeks backordered. Clearly, despite the ability to pirate their stuff, they still make sales.
Same deal with Cakewalk. Sonar has minimal protection. That is part of why I buy it. I appreciate not getting jerked around with DRM, I want to just use my software. I'm not as anti-DRM as many but I still appreciate things that don't have it, and it factors in to my purchasing decision.
So just make sure you consider everything, and keep your eye on what matters: Increasing profit. Decreasing piracy doesn't matter if it doesn't lead to more money.
I like to give an analogy of a retail store: Shrinkage (shoplifting) is a big problem for all stores. Unlike piracy, there is a direct cost for each item stolen. Well, a store could probably stop it completely if they wanted to. Hire armed guards that strip search all customers and employees going in and out. That would probably do it. It would also lead to there being zero customers, thus no revenue, and so be a losing proposition. All the steps stores do take against shrinkage are weighed against costs, both the direct cost to implement the measure and the cost of customer satisfaction. The balance they strike is imperfect with regards to stopping shrinkage, but best for making money.
NI may have weak DRM. They also have $750 of my money recently because they have good products, more than that if you count the license fees they got from 3rd parties I also bought. EastWest has much better DRM. They have gotten zero dollar of my money recently and will not be getting any because their software sucks.
