I appreciate your response, but I find it frustratingly vauge. What kinds of bad things happen to open source projects that drive them to this? If you are fearful of open source becoming more closed, why are you promoting that very approach?
Did you consider promoting alternatives like AGPL first? Before I see an option violating one of the four essential freedoms I would really like to see a detailed exposition on why the AGPL or other approaches discussed in my article are not suitable. I don't think that the brief summary on AGPL on your website is detailed enough - it doesn't have any specific criticisms of AGPL.
The problem with "needing to change their license" is that it's really just a few people who "need" to change it. In reality, open source projects are community works, and even the maintainers don't have the (certainly moral, and usually legal) right to change the license.
I think your Commons Clause gives vulnerable people (open source maintainers struggling to make ends meet) an easy but despicable option for their projects. Especially in cases like Redis, where a company has ulterior motives and employs the maintainers, they can strongarm maintainers into making choices which are not in the best interests of the project.
