Again, this does NOT make it so "only the authorities" can detect it. All it's doing is disabling bluetooth broadcast mode and enabling WiFi broadcast mode. WiFi mode makes it very difficult, slow, or impossible for most of the consumer smart phone apps to detect. Wheras the consumer smartphone apps can rapidly and easily detect the bluetooth based RID broadcast.
Nothing about this has anything to do with WHO can detect the RID broadcast. It's WHAT can detect the RID broadcast. Most neighborhood Karens aren't buying expensive RID receiving hardware. They're using a smartphone app that works efficiently and effectively with Bluetooth, and slowly or not at all with WiFi broadcast.
It is an effective way to reduce or eliminate smartphone app RID broadcast detection TODAY. But that's only because the technology, apps, and costs are limiting it. Not because "only the authorities can detect it".
