What I proposed is this, with a compromise that’s an explicit board seat and still required to sit out when there’s a CoI. I’d strongly suggest a blanket ban and removal of the explicit seat over allowing shareholders of recipients to sit on the ZF board.
There are easy fixes for this in the other direction – board members should divest ECC holdings if they want to keep sitting on the board. I prefer an orderly board refresh and a more “professional” board rather than one that’s so heavily weighted toward researchers and founders today, but either can happen in my proposal (or another) and give us two arms-length organizations.
