As the case is currently before the courts, I'd advise that extended comments and opinions about the case and the charged individual should be restrained until the case is heard and judgement handed down.
Discussion of pending cases on "social media" is nowadays considered to possibly be interference in the case, and can land social media commentators in hot water via contempt of court charges.
The AFP have all the facts and information on the case as we currently know it.
It is obvious that the AFP regards cases of ATC and airliner communication interference, with the greatest gravity - and I believe this is correct and in line with the intent and meaning of the laws associated with the charges.
The potential penalties for the offence/s reflect the gravity of the offending.
