> Reuters states that since Starlink officially registered its business in India on November 1st, it has already seen over 5,000 preorders in the country [0]

That's from The Verge's article a few days ago.

> And if Starlink did start broadcasting in Indian airwaves without a permit (not really possible since they’d need a ground station but assume they place some ground stations around India’s borders)

They don't need to. It could just as easily operate from across the border, the ground station I'm connected to is in Canada even though I live in the United States.

Maybe if they had a geostationary satellite, sure. Starlink is a LEO constellation though, so if they took down a satellite this weekend, SpaceX would launch 60 more by next Saturday (and service wouldn't be interrupted since there's considerable redundancy built into the system). Unless India intends to take out a few hundred satellites and be responsible for potentially catastrophic space debris, I think it wouldn't be a good opportunity for them to test their anti-satellite weaponry.
