Interesting point here. But it forgets that it is a well known reality from software vendors, who basically choose how well protected their software can be. As an example, an interesting move was Apple's one with Logic Pro. I remember previous versions being uncrackable, needing a USB dongle. And then, as a move to conquer market share, the only protection is now just a serial number (I'm not even sure if Logic calls home to check it... ). The more people can use your technology for free in a training / learning / amateur way, the more you will become a standard, the more you will sell licenses to your customer base : the professionals.
