I wouldn't describe all opponents of Open Flarm as technophobes - some are (and have admitted to me that they are "not computer people"), other like technology just fine but seem to feel that some skill they have (perhaps risk-tolerance is one) will be diluted with new and better information. But denying people all external information hardly seems like a fundamental principle of glider racing - if it were we would do separate time trials or all MAT format to maximize the separation of gliders so you can't use any visual cues. We would have leeching penalties that are quite easy to calculate with IGC files. We don't, and no one seems to be interested in going down that path.

While maybe not a "fundamental principle" one might look to the rules that have been in place and withstood the test of time.

6.6 Restricted Equipment
6.6.1 Each sailplane is prohibited from carrying any instrument which:
* Permits flight without reference to the ground.
* Is capable of measuring air motion or temperature at a distance greater than one wingspan.
6.6.2 An external cleaning device is any device with moving parts designed to clean the exterior of the sailplane during flight, such as bugwipers.
The use of such devices is allowed in all classes Rule 6.12.
6.6.3 Carrying any two-way communication device is prohibited, with the following exceptions, each of which must be a standard,
commercially available model that is not used to provide any in-flight capabilities beyond those referenced below:
6.6.3.1 An aircraft-band VHF radio
6.6.3.2 An aircraft transponder
6.6.3.3 A wireless telephone (which is not to be used during flight)
6.6.3.4 A air-to-ground position reporting device
6.6.3.5 An anti-collision device. Rule 6.6.3 does not forbid the use of a standard GPS output data stream or GPS log produced by the
device.
6.6.4 Other than an aircraft-band VHF radio, any device that allows in-flight access to weather data is prohibited.
6.6.5 Violations of any provisions of this Rule are considered Unsportsmanlike Conduct. (Penalty described in Rule 12.2.5.3.)

Note that the rule was added a few years ago to permit a collision avoidance device. We have a pretty good one of those in Flarm. They do not expressly permit a device for tactical tracking or viewing our competitors which turns out to be another very useful application of the device. This is what I might call a "back door benefit" of the use of Flarm which could reasonably be seen as not included and thus either removed(not possible without destroying the benefit of safety), or limited in some manner.
The rules also are clear in intent to limit information in to that which is described in the text.
For 2016, phones will now be allowed to be on for the purpose of enabling tracking outputs only.
So while you might want to roll over the top on this and create a wide open cockpit technology race, the process will require a measured pace which starts with no new information in until due process allows it.
