The Avdata system isn't perfect. Technology that photographs the aircraft will be more accurate than the voice recorders which allow for people to be dishonest by using false callsigns or not saying anything at all.
The elephant in the room is the RA-Aus registered aircraft whose owner details are not made available so they can't be invoiced, unless this has changed recently. So they are being subsidised by everyone else who owns or uses the facilities. If you want to make a fuss then make it about that. Avdata on the whole do an OK job.
