It is. The person you're replying to was naïve, and still is. It's true: Adding stuff to Wikipedia or OSM can help bad guys get information, and this can have negative effects for you. But the person you're replying to assumes naïvely that this is perceiptibly worse than the negative effects of bad luck. You're going to have bad luck in your life, that's in the nature of luck. I added the location of a specialist shop that sells mostly grappa. Someone might find that shop with the information I added, buy and drink too much grappa, drive a car and drive over me. It could happen. But thinking that this is perceptibly worse for me than if I hadn't added that location is naïve. Similarly, your country could introduce a retroactive law prohibiting proxies or introducing some form of liability, and when the Iranians send a list of IP addresses your country gaols you. It could happen, but is it probable enough to be compared to the effects of bad luck on your future life?
