That's an interesting argument, however it probably wouldn't go that far.
Taking it back to retro interpretations, sharing your photo with meta is basically the same as sharing your photo with a print company that takes and processes your negatives. They're acting on your behalf in a limited scope, so sharing with them is the same as you doing it all yourself.
However it maybe comes back into play when that scope isn't limited, as Meta require in their terms of service. It doesn't matter what individuals say to Meta regarding their data, their prohibition is superseded by other users, who agree that they have permission to share other people's information with Meta.
Meta isn't breaking privacy laws - you are.
Sounds like the Ukrainian radar bit is a side note, the main thing is that they don't have to visually identify objects. This means they don't have to scramble a jet to intercept before firing.
However the downside of this is that it dramatically increases the chance of shooting down the wrong aircraft.
