Criticism and controversies Google has had criticism over issues such as aggressive tax avoidance, search neutrality, copyright, censorship of search results and content, and privacy. Other criticisms are alleged misuse and manipulation of search results, its use of other people's intellectual property, concerns that its compilation of data may violate people's privacy, and the energy consumption of its servers, as well as concerns over traditional business issues such as monopoly, restraint of trade, anti-competitive practices, and patent infringement. Google formerly complied with Internet censorship policies of the People's Republic of China, enforced by means of filters colloquially known as "The Great Firewall of China", but no longer does so.
