Why can't other broadband users defend their rights when residential broadband is monopolized?

Complaints about property and operators must first understand whether it is because the operators have not covered resources or because the property has to charge an entrance fee. It's easy to understand. If you complain about the property, you can go to the Property Office of the Housing Authority to complain about the operator. You can call customer service (but it is generally useless to call customer service) or log on to the website of the Ministry of Industry and Information Technology to complain.
