What prize and business interest are you referring to? The Mozilla Corporation is a company that must answer to its shareholders, and its only shareholder is the Mozilla Foundation. The Foundation, in turn, has interests determined by its board, and "an internet that includes all the peoples of the earth — where a person’s demographic characteristics do not determine their online access, opportunities, or quality of experience" is one of those interests (added formally to their manifesto in 2018, but likely the guiding idea behind the Eich matter).
You could certainly disagree with the interests of the Mozilla Foundation's board, and could choose to support another organization, like Brave Software, that has different ones, but are you suggesting that a board should not be able to determine the interests, within legal limits, for a non-profit, or that the sole shareholder of a corporation should not be able to control its interests and mission?
I'm not sure I understand why establishing social values shouldn't be a vital component of any organization, particularly a non-profit organization dedicated to equality and openness, that employs a large number of people and relationships with the public and any number of third-parties? I'm actually not sure it's operationally possible to ignore them as a large public organization. Further, how much time and resources do you think it really takes to identify and define a code of values? Seems like it wouldn't necessarily require the full-time focus of even one member of staff and the very occasional meeting.
