That roster includes O3B mPOWER (SES), Inmarsat, Kuiper (Amazon), OneWeb (UK et al), Guowang (China) and Sfera (Russia). I doubt they are so easily intimidated.
Umm, they are already pretty intimidated. As Starlink stands right now (in beta with partial constellation in service), it's superior to all of those combined. Those guys are shitting their pants right now scrambling to either block SpaceX from moving forward (by whining to authorities) or setup their own competing constellations.
