If a number of people(experienced/experts in a field) are willing to volunteer their time and/or capital in exchange for equity/patents/stock, then it's all good. My problem lies with externalizing the cost and risk to employees.

If they need something done and they can't guarantee long-term employment, they can buy commercial services for what they need. Engineering firms and temp offices will be happy to send you a secretary, a software solution or a CAD file with what you asked.
