Call me cynical, but you are absolutely clueless. Once shareholders are involved (especially public) the management will be changed. This lovely piece appeared about a week ago here on HN:

The RPi founders will be sacked in favor of profits. All those charitable things done for free will be stopped. The $35 Pi - nobody will mind if we raise that to $50. All sorts of things will change. Maybe not immediately, but they will change. The profit motive goes directly against the notion of a "non-profit" organization. Shareholders want ROI. End of story, end of Pi as we know it.
