You clearly don't understand that investor expectations are not written in the contract and do not take into account every minutia of what changes over time. It is based on general expectations as a shareholder and what that entails. The company cannot thwart that general expectation that a shareholder is a part owner of a company and entitled to a share of the profits, as dictated by business results.
Yes, and even with those expectations, the NWS was a BREACH of the shareholder agreement. Now that it is established that it was a breach, we don't suddenly expect more breaches to be "ok" since there was one in the past.
