You bring some valid points. As long as we don't go back to the nag-screens of shareware, I'm excited to see conversion attempts made in novel ways.

If a product is of value to me I will indeed pay for it, if I can connect to the developers, I will pay even more. That's where choose your own price really gets me, I often pay more than typical.

However it isn't true across the board.

Regardless, I have read that many companies which experience vast piracy of their products, e.g. Adobe, make much of their revenue from other businesses. Is this true?
