Mike, thats sounds pretty hypocritical coming from you.
You of all people should be honest in acknowledging the challenging business economics that are apparent in serving what is a tiny community. Flarm have done a great job over the many years supplying a reliable, life saving product that cost less than some of your Varios. Like you Mike, they have every right to protect their IP and make a living. I don’t see you rushing to Open Sourcing your codes. Open Source has its place, as does Proprietary supply. Right now, Flarm licence their code and design to 9 other parties. Those parties add their own value into the supply chain. As such, its a competitive market. > On 7 Mar 2016, at 10:32 AM, Mike Borgelt <[email protected]> > wrote: > > At 07:45 PM 3/6/2016, you wrote: >> On 6 Mar 2016, at 2:30 PM, Richard Frawley <[email protected] >> <mailto:[email protected]>> wrote: >> >>> http://flarm.com/statement-by-flarm-technology-about-recent-unsolicited-emails/ >>> >>> <http://flarm.com/statement-by-flarm-technology-about-recent-unsolicited-emails/> >> Smells like bullshit. >> http://flarm.com/wp-content/uploads/2015/08/FLARM-System-Design-and-Compatibility.pdf >> >> <http://flarm.com/wp-content/uploads/2015/08/FLARM-System-Design-and-Compatibility.pdf> >> >> >> "Encryption of the radio protocol is a consequence of the requirements for >> privacy and security and was thus introduced nearly a decade ago: It >> protects the system from abuse but also from rogue devices implementing the >> protocol and system incorrectly or incompletely.
