Google is either actively malicious to the open web, or doesn't care about it other than as something they can strip-mine as a revenue source. They sufficiently diversified into mobile and Android that the death of the open web would be but a blip to them.
IMO, Firefox should consciously be that alternate source of authority. How they accomplish that organisationally is irrelevant, what is relevant that their browser as a whole is competitive and focused enough that it stops haemorrhaging market share, and can start to slowly rebuild it as people look for a way out of Google's ecosystem.
