is an intended recipient,
This is really interesting. The 'intended recipient' of my ADS-B 'out' transmissions is anyone in the vicinity who is airborne or another agency on the ground using the information for my benefit. This includes someone in the clubhouse looking at FR24 to see when the aircraft will be back for sortie planning purposes. In order for this to work, the information needs to be presented on a web site via the internet.
Someone needs to bring a test case to see if transponder transmissions are covered by the definition 'wireless telegraphy'. Strictly, 'telegraphy' means 'the long distance transmission of written messages' (from the ancient Greek).
It's also interesting that in the US (and Canada it seems) we can listen to ATC voice transmissions and get an instant replay on social media whenever there is an accident or incident, whereas in the UK, you never hear a peep - probably due to people being afraid of the WTA 2006.
Freedom of Information seems a lot free-er in some places than others...
