[Brainstorm & Review] Monetization of open-source development proposal

Hello!
I have an idea of how to monetize open-source development - I guess, it would be interesting for community.

Free software is a matter of liberty, not price. To understand the concept, you should think of free as in free speech, not as in free beer. (Richard Stallman)

I’ve created a repo at Github to describe the idea, it contains minimal piece of code to explain the point.

There are already several issues created - please take a look.
I need community brainstorming & review, whether it is appropriate way to monetize and if not - why and how to transform it to the desired way. Or should we completely abandon this opportunity - it could be the option, I just want to get a clear insight why.
Though it is written in PHP and is related to Composer - the idea could be easily adopted to any environment, which has unified package manager. Please don’t hesitate to join any discussion (issue), they are language-agnostic.
Thank you for your attention.
