Why have the Yellows been so quiet about Malaysia's expansionism in the Spratlys?

The Yellows keep ranting that President Duterte hasn't continued to quarrel with the superpower China to assert our sovereign rights in our exclusive economic zone - ignorant of, or rejecting the fact that not just China, but Vietnam and Taiwan are claiming not just rights but sovereignty over those areas our EEZ encompasses. Thus, as Duterte succinctly put it, "China is claiming it. We are claiming it."
