But do they feed it back to the fabricants already ?

I'm sure the navy is aware of the threat and has standing procedures to prevent it - afaic high-ranking officers were sacked precisely because those weren't being properly followed. A huge container ship in a space as tight as the Malaga strait otoh probably has no procedure to deal with GPS being abruptly and subtly spoofed or even a way to detect it.

It's not deceptive as much as it is dumbed-down and devalued as a tool for increasing scientific literacy and curiosity - at the very least the image should have included a distance and radiation energy scales - preferably several at different distances from the event horizon to account for GR. As it was released the xkcd comic of it provides more value than the image itself.

Time to update the odds that the two accidents involving navy destroyers in the Malaga straits, weren't ?

Mind you this does not automatically implicate Russia, just because one report calls them pioneers doesn't mean other countries don't posses the capability and China has more concrete issues with US naval presence there than Russia.
