I was looking through a couple posts that had on-board pictures of the ISS and noticed something almost immediately:
They have information (which could be sensitive) shown on the laptops:
While blurry, it doesn't seem to be being actively blurred out; rather, just because it's not in focus, it's hard to read. I'd imagine there are shots where things could be read. Is there anything they do actively to prevent ISS data from being leaked to the public through photos such as this? From the photos I've seen they don't even lock the laptops (I've not seen any with the windows lock screen).
Example of a blurred screen from @uhoh:
I believe I can edit the question to ask, when and what are they concerned with blurring out? It seems inconsistent. Who makes the call that the data is sensitive enough for a blur?
