So what?

Have I said that it's bad or good? I was just pointing out that yes, apparently data like this does get used in for bad things. I am not judging, as you seem to assume, I'm pointing out.

It's a pity that others aren't as broad minded to consider both or all sides of technology. Technology isn't always automatically an improvement of the current situation. Yes it might solve the obvious problem but there are also side effects. Social media, for example, is a good demonstration of a bunch of side effects that weren't intended.

And so it is with open infrastructure, it can have unwanted side effects and we should be aware of those instead of hand waving them away. Mitigation here is difficult: open access and meshing up of data is important and should be encouraged. Hiding this data away won't help.

If you are not interested in disrupting the grid then yes - you implied it’s bad. You only mentioned the bad sides of such info being widely available.

And like already mentioned in more nested comments - it’s not difficult to get such info if you are determined enough.

…and then you go on to imply it has bad side effects. But you haven’t actually made that case. Do you really believe that a hostile group would have difficulty finding important infrastructure to attack without an open infrastructure map?
