Look bud, I understand your frustration, but as a capitalist I'm going to give it to you straight:

They created the product, so that means they also reserve the right to charge you whatever you want, whenever they want, and for however much they want. But as a consumer, you also reserve the right to NOT buy their product. Nobody is holding a gun to your head and forcing you to pay the money. In purchasing the HardSPL, you are paying for a luxury item that most of the public does not own. And if you don't like it, then you also reserve the right to write a HardSPL unlock code yourself and enter the market as their competitor and offer your unlocker for cheaper or even free

Look, fact of the matter is, they created a product and reserve the right to charge you for it. And by no means should they be forced into offering it for free. I know you feel that you already paid for it, but their terms are clear up front that you will need to pay for multiple devices. Arguing that "you already paid for it once and that should be enough" is akin to saying "I paid taco bell for that burrito last week, but I'm hungry again so they should give me free burritos for life since I already paid for that first one..."

Sounds ridiculous, I know, but my point in that analogy is that you are asking to unlock a second (or third, or fourth) device and, per their terms, they can charge you for it.

Again, if you don't like it, then don't buy their product or support them (or, even better, go write your own code and set your own terms)
