The internet will be a less free place when there is only one browser and one search engine (in practice), one video upload site, one mobile OS all produced by a company with a "do evil when the shareholders demand it" policy
While I agree, I don't see Mozilla in its current incarnation being a viable competitor to Chrome. It's unfortunate, but it is only one of many experiments in not-for-profit organizations, technical and otherwise, becoming obsessed with politics over product or service.
Perhaps this is a human foible; those whose interest is in setting goals for others often seem to find a way into management of non-profits, using the bottom-up philosophy of management, while for-profits' goals are set by directors who represent bankers and come down from on-high, using job-insecurity as an enforcement tool. Bankers don't change their goals, typically, over time, while not-for-profits' goals can change on a whim, apparently, if enough people back that whim.
There must be a synthesis hiding somewhere....damned if I can find it, though,
