Please keep in mind that the UN is an arena for international cooperation. A lot of organizations fit under their umbrella, which does everything from coordinating the global mail system (UTU), international telecommunications (ITU), maritime safety (IMO), international civil air travel (ICAO).
Any country can join these charters as long as they follow the rules agreed upon. What good would it do if you couldn't send a letter to someone in a country under dictatorship? Or if we stopped eradicating polio because the remaining countries are deemed unworthy?
The UN is not this singular place, where you can get "a vote". That is true of the general assembly, but they presumably had nothing to do with this report.
