I really do not see the issue. The difference between a non-profit and for-profit owned by a non-profit is basically nil in my country (Sweden).

The board and managers of Mozilla Foundation being unethical does not have anything to do with the existence of Mozilla Corporation or not, that is just minor administrative details and they could be just as unethical either way.
