This might not be appropriate for your case, but piracy can be considered a form of differential pricing. Student movie tickets are cheaper, even though the seat taken is the same. This is done so students will spend some money instead of none, without reducing the price that other segments will pay.

They may later become paying customers. It denies oxygen to competitors. Apparently, adobe turns a blind eye to piracy of photoshop, for reasons like these. But to repeat: this mightn't be appropriate for your case. Are there such network effects? Would you benefit from them, over time? Is there some trigger for actual purchase?
