So, as I understand it, the current situation with the Open Glider
Network is that:

It relies on tracking Flarm collision data against Flarm's wishes.

It relies on using the Flarmnet database (which is encoded so that
the database can't be downlosded and be easily human readable)
against their wishes.

It relies on a free-to-OGN network of ground receivers that have been
voluntarily set up and funded by glider pilots (including myself who
has funded one) to receive Flarm transmissions.

Now the OGN want to sell us commercial transmitters

Hmmmm.

Flarm radar has been extremely useful and fun in the last year in
Europe but we glider pilots collectively own the vital ingredient which
is the ground receiver network and I for one wont be buying a tracker
from the OGN in those circumstances.
