I don't think such a thing exists. It's a pretty niche topic. The Mozilla foundation is a non profit which owns all of Mozilla corporation. Because foundation is a non profit, donations to it are tax deductible. They also cannot funnel money into corporation, either, as a result. It's not that easy to be a tax evasion vehicle. It does mean that the corporation is not beholden to external equity owners; its just beholden to the foundation. But the corporation is also 100% for profit, although they evidently struggle to earn said profit. Mozilla isn't quite a non profit nor a for profit company in aggregate as a result.
