Now I understand, thank you very much.
Well it seems OGN is going to pay back the privacy issue. Their OGN tracker
is going to expire in a few days, and they will now pass through Flarm to
get the data decrypted.
Stealth mode was easy to accomplish, very strange, and a very sad
conclusion. But I agree that the privacy goes first, it wasnt that hard to
deal with, at all.

There are a lot of people here in germany who don't want to be tracked or at
least want the freedom to decide. This kind of stuff really hits a nerve
here and there was one of the longest threads I have seen sofar in the
german gliding forum. There was a big outcry for an opt out option.
Unfortunatly not all OGN operators feel there should be an opt out option.
The problem seemed to be that OGN is an initiative of individuals. That
means there is no central entity to discuss privacy requirements with or to
enforce an opt out implementation. So basically it doesn't help that the
solution might be technically trivial.

Tracking of individuals without consent also might touch strict german data
privavcy laws - even though it would need a court ruling to clarify whether
tracking a glider is already sufficiently linked to the piloting individual.

It seems that Flarm and also Butterfly Avionic (removing FlarmNet databases)
took this topic quite seriously. In the end Flarm chose to end the
discussion by taking the intiative. A new encryption should disable OGN
short term and long term a Flarm organised solution will probably transfer
OGN operators into Flarm control enforcing opt-out.
