He describes his vision for "post open source" license, which he is currently developing. His goals seem to be to to empower software developers to take back power from megacorps which have in his view subverted the nature of open source and turned it into a "resource extraction" scheme.
We already have some copyleft licenses that prevent the kinds of proprietary SaaS usage that have prompted recent complaints. People and projects don't use those licenses; they use permissive licenses, and then get surprised when companies use their software under those permissive licenses. I've even seen people complain that if they use copyleft licenses, large companies won't touch their software. That's entirely the point! If you want companies to pay for an alternative license or an exception, you have to choose an Open Source license that they're not already willing to work with.
Before we even consider giving up on the Schelling point that is Open Source, perhaps we should make better use of the full spectrum of Open Source licenses we already have.
