That's correct, which is why we are focusing specifically on R&D fabs. But perhaps there is also a way in which some commercial fabs could be incentivised to enter into partnerships wherein they could open source PDKs for a particular node, like Skywater Technology has done with Google for their 90nm process.
PDK is an IP. I don't see any incentive for companies to make it open source.
