A high degree of transparency is necessary for a “company owned by humanity” to be managed by the public. When such a company hires people or serves customers, how can their right to privacy be protected? How should sensitive information and company secrets be handled?
It would probably be necessary to make certain information within the company accessible only to a small group of people who undertake to treat this knowledge confidentially. Perhaps it would make sense to have these people elected by the community. However, it must of course be ensured that these people are trustworthy.
