But then how would they be able to sell your location data? It’s a crucial revenue stream! /s

They do sell a tool to police and governments that allow them to track drone operators. The Ukraine military uses drones extensively to monitor the Russians from the air and assist with artillery accuracy but any time they would launch a dji drone Russia had access to that software and would send an artillery shell to the pilots location.

Russians, like Ukrainians, and all other government forces in the world, have extensive experience triangulating transmitted signals in warzones. Considering that these drones rely on bidirectional communication, it is obvious where the pilot is without hacking DJI. A drone operator in a warzone appears like an active microwave oven with its door stuck open operating from a deserted area. Militaries can triangulate those signals for decades.

Exactly.

During WWII the already had radars enough to detect periscopes sticking out of sea surface from tens of miles.

They were also able to triangulate subs by their short transmits anywhere on the Atlantic with pinpoint precision.

People very much underestimate technical military capabilities.

The issues with militaries are of a different kind -- sifting through deluge of information, prioritising, making right inferences, etc., not the ability to spot and triangulate the enemy.

I think periscope detection is only possible since the 1970s

  The opportunity to detect periscopes was exploited in early radar experiments that prompted the development of the AN/APS-116 radar manufactured by Texas Instruments in the 1970s. The AN/APS-116 is an Xband, high-resolution, fast scanning system developed specifically to provide a periscope detection capability on the carrier-based S-3 aircraft. The AN/APS-137 is an upgrade of this radar used primarily on the S-3; a limited number are also used on the land-based P-3 aircraft.
