Linlin's 2nd or 4th Commander was defeated by Kidd, her territory was raided/infiltrated succesfully. An important target was stolen too.
Linlin's 1st and 3rd Commanders were defeated by Luffy, her territory was raided succesfully by SHs + Firetank Pirates + Germa.
Castle destroyed in the process.
Linlin herself was defeated by Kidd & Law during Onigashima night, same happened to her first son Perospero.
It happened at stages, but the Big Mom Pirates have been slowly defeated and thorn off that throne. It makes perfect sense for them to be out of the Emperor system since this is based on credibility/propaganda too.
