Authoritarian - a corporation is directed in a completely top-down manner, with singular authority vesting in the executive.

They obviously exist within a larger society where workers are free to quit, have some rights that can't be taken away, are bound by agreements, etc. But the organizational structure itself is strictly hierarchical.

The problem comes when these assumptions are baked into systems that are supposed to serve wider society. A corporation can tell their employees that they must use only certain computers to do their work, modify those devices, revoke access on a whim, etc. Whereas in wider society, relationships should be that of independent peers interacting through well-defined protocols, with each party free to make their own choices.
