Basically, he advocates a new license that he wants to develop that basically improves remuneration for open source developers. Use case: A "Post Open" software is used by a company, then this company has to pay a certain percentage (1 to 10%) of their revenue to the "Post Open" software. If it is using multiple "Post Open" packages this percentage is divided among them (according to usage).
Software in this scheme will be allowed to be modified, redistributed etc. and it will also contain a public API that defines the boundaries of the program (so it's not about linking anymore).
I hope that captures the key points.
Even if there is only a single "post open" package which gets the full 1% of the rev share, what about one developer which contributes a whitespace or spelling fix, versus another developer which contributes a key part of the package? What if one developer contributes a huge number of lines of code, but it's for a feature which isn't actually used at all by a particular billion dollar use case of said "post open" package?
The devil is really in the details.....
