It's not a question of being a geek or having any connection with DSX.

The real issue here is that FAI rules should be that you need an anti-collision system instead of oblising the pilots in competition to use one specific brand. They should define a common protocol so anyone interested can develop its own product.

A valid example is for the flight recorders. You do not need to buy a flight recorder of a specific brand. There is a standard format (IGC) defined by the authorities.

For sure I do not like monopolies....
