Look through the code and you'll *always* find their secrets. Simple fact. Like I said- once I purchase the software, I'll go through it. If there is a 'back-door' or 'call-home' feature, I'll null it. Once purchased, it's my software and therefore, my choice. No 'call home' feature. No 'back door' feature. And these types of features would need to be publicly disclosed (if they exist, at least) I think.There are many ways to make nulling very difficult. The ultimate trick though to end up letting the nullers null the product but in a way that still calls back to the server so they know exactly who the nullers and pirate users are and can pursue them legally..
I am 100% positive they won't share this secret though as the whole point is that you shouldn't know about it.
