Is there freely available data on commercial & private airplane movement in India, China, and Russia? I'd be very surprised by that.

Yes, although coverage is probably lacking in rural areas (eg https://globe.adsbexchange.com)

I'm surprised how good the coverage is over the mid Atlantic, far away from any hobby ADS-B receiver.

If you click, you’ll see it’s mostly sat ads-c:

Thanks, I was not aware that even existed. That's a nice rabbit hole.

I see dense coverage on flightradar24 over India, China, and Russia. Can't say how complete is that.
