"While with the paid software, all of the interactions I had were so much more constructive. YMMV, but willingness to pay is a great filter."

That's in line with my experience on both consulting and selling software. The more they pay, the easier and reasonable they are to work with.

Years ago, I put out some free software and there were a lot of users who seemed to be on a power trip to show me who is the boss. I assumed they were some lonely guys in a basement who had nothing else going on, so they best they could come up with is to beat up an author of the only software they can afford.
