As a member of GalGov, I can say that Govs decide themselves whom they want to see and whom they don't. LibGov and GalGov have votes and discussions, other Govs may have other means to decide on such things. Devs dictating to players what they MUST do is harmful for roleplay, forcing un-wanted people into Gov changes nothing as those people can be just ignored which leads to more drama, leaks etc.
