The profits are owned by the Corporation, which is why the Corporation does all the crazy spending and paying millions to executives, because as long as there is enough separation what they do internally does not affect the tax situation of the Foundation. After the for-profit pays taxes, the non-profit can get dividends and other payments from them, but it is not just a way to wash away tax from all the money.

The Corporation acts like a company because it is one. This is different than Konqueror, Epiphany, or most of the Firefox forks.
