High profile aircraft (ie Trump Force One) tend to ask for their data to be scrubbed from these sites and the sites typically comply; however the data from those planes is still transmitted unencrypted over open airways for anyone to listen in. A network of people who share data could reconstructed and view the data that others wanted removed from public view.
