To be unfairly cynical here, the sentence you quoted sounds to me like "I chose to not have a front door. I didn't give it much thought at the time, but knew that I wanted my home to be available for people to learn from my interior design choices and decorations. Then I discovered that people walked in, started to eat out of my fridge, leave dirt everywhere and carry off some of my chairs, and it hurts".

The fault here lies not with the persons who use the maintainer's code exactly in line with the license, no matter what other _intentions_ he might have had.
