People with owner or team maintainer permissions can remove team members from a team. This may be necessary if a person no longer needs access to a repository the team grants, or if a person is no longer focused on a team's projects.
Warning: If you remove a person’s access to a private repository, any of their forks of that private repository are deleted. Local clones of the private repository are retained. If a team's access to a private repository is revoked or a team with access to a private repository is deleted, and team members do not have access to the repository through another team, private forks of the repository will be deleted.
