California has passed a law requiring bots to disclose their artificial identity when used to sell a product or influence a voter, with violators facing fines under state statutes related to unfair competition. The law aims to reduce the power of bots in politics and commerce by bringing transparency to their use. The legislation was opposed by tech companies and digital rights groups, who argued that it could stifle free speech and silence beneficial bots. The law only applies to bots used for commercial or political purposes, and does not ban them outright.
