I would take issue with this as the commercial success of Raspberry Pi has enabled them to do so much more than they would have otherwise. Look at it as a nominal vs real problem. In your version, success leads them to focus more on trading, clearly to the detriment of "doing the world a favor". In my version, commercial success a) provides previously unimaginable levels of funding for the foundation, and b) puts more Raspberry Pi into the world, which in its own right furthers the goal of increasing child computer education simply by making them more accessible.
