One might think that the developer of the application is the right person to pay for the application.

Why is $2 going to some ppl who made something which provides you with value >2 everyday,(or some random value), the wrong people?

Extend the analogy only a little, "I dont buy anything on the internet as I want some of it to go to Tim Barnes Lee."

Indeed. This is the crux of our news organizations' current crisis. They create and organize the content, yet everybody else is using the content for profit. I choose to reward those who create and organize the content.

The delivery of content is extremely easy, especially for me since I'm a developer myself.
