Why do cities adopt home rule

With Home Rule, municipalities take themselves out from under Dillon's Rule - the prevailing legal doctrine which states that municipalities only have the powers given to them explicitly by the state - and instead allows them to create a form and structure of governance of their choosing, so long as they do not conflict with state or federal law.

which have adopted a home rule charter for their local self governance.

so what they are saying is the citizens of a home rule city are free to choose their own form of municipal government.
