If anyone is interested, you can build your own adsb receiver for very cheap (under 50$), and you can forward the data to all the platforms - ADSB-exchange, airplanes.live, flightradar, flightaware, etc.

You'll get the business tier plans on the commercial sites for free, and you'll feed the community exchanges.

You'll also be getting the data directly, so they aren't censored, and don't rely on the internet.
