I’m going to reply here.
These are effects of a connected society, I’m unsure on whether they are a net good socially but technologically and economically they have been a game changer.
This has nothing to do with a surveillance state, it might enable it but it enables it in the same way any technology enables the ability to abuse said technology.
The “state” didn’t publish or share the photos.
The things you should be complaining about is the state passing laws to get arbitrary access to the cellphone location data of every single person at this event, and being able to link that data to an individual. That is a loss of anonymity that can be a vector to prosecution and you should fight about, and has nothing to do with the information.
And yes and 5/13 eyes country can and will get that information if they so desire and will likely even share it amongst each other and the public would not need to be any wiser.
If you are on the “state”’s radar they can absolutely track you to within a few meters across international borders. Technology enabled this, “the people” allowed it. A coldplay concert exposing an affair is unrelated.
