Now all we need is the open hardware itself. Private manufacturers simply don't have any incentive for this. It has to be state or non-profit funded, but those have problems with attracting and retaining talent, as well as the existing IP issues. Any open hardware will likely face IP lawsuits and WTO sanctions.
There is a lot of open hardware, also a lot published by private companies.
