From a 'security' perspective, this seems like an objectively good thing to me. If having this data publicly available is a good thing, then this map is a good thing - the more exposure, the better. If it's a bad thing, then the higher exposure resulting from this makes it more likely that a change in policy will happen.

The status quo (prior to the publication of this map) was that the information is publicly available but only a few people were aware of it. I can't imagine any argument for that being the optimal situation.
