At this point you're getting to a level of technological sophistication that would make widescale adoption in authoritarian countries unlikely. The whole point of the article is that you don't have to completely block something, just make it too annoying to use for the average person.
Edit: actually, an even easier solution for the government would be to perform uplink jamming of starlink satellites. Any satellite that orbits into sight of an authoritarian regime gets a directional antenna pointed at it that pumps noise into its receiver and keeps it from detecting base stations on the ground. Once it orbits out of range it continues to operate as usual. Since no satellites are damaged and only operation above the authoritarian country is effected (since starlink operates at LEO and each satellite only sees a small part of the Earth's surface, compared to jamming a geostationary satellite that would knock out service on an entire side of the planet) there would be significantly less political pressure to stopping this jamming.
