@skyfaller Indeed, we'd prefer that these projects remain under our auspices, open source, and unencumbered by a CLA.
For the avoidance of doubt, the Foundation's mission and rules forbid us from acting for the private benefit of any party, and as such we cannot contribute anything that requires us to sign a CLA wherein the assignment is made to a privately-held entity.
We are committed to building up the open source commons around Matrix.
