some reasons for using a cracked version of any game engine or design software having a per seat licence:
- to postpone buying a licence, until game is ready to sell, thus shorten the investment time. this may have a positive effect on selling the most expensive edition: e.g. each Unity Pro update is cracked and available easily (I don't know how stable they are)
- for toying a cracked version is okay, but those people would never buy any licence I think
- imo a one month trial period is short for testing all the features of a totally unknown and complex engine

3dgs licensing policy is not bad, you can upgrade as you improve, but I agree the Pro is a bit over priced, this is the stage where I think of switching to another engine...
