If 90% of the nodes are controlled by Google, then I think the answer is clear that you do NOT in fact have a distributed system. If this occurs, then the system was not designed well and should be abandoned for a new one. Agreed, you want the nodes to be controlled by many different entities globally, but that should be a function of the technical implementation of the distributed system rather than having to identify a responsible party that is accountable for this objective. Privacy is crucial to ensure a distributed system continues to function; otherwise, orgs or individuals running nodes could be censored in mass by authorities or participants may stop using the system due to security concerns.
