Ulf, thanks bring me up to speed. I'd love to make this happen, so I've written some responses inline.
*TL;DR;* I disagree with privacy concerns raised in the PR and (in my non-legal-expert-opinion) think we should be able to do this w/o affecting user privacy or complicated workarounds.

Though I'm reluctant to, I'd like to revisit this debate because I feel we'd be adding a non-trivial amount of complexity (maintenance cost) to the app when it can be avoided. First, showing a map with annotations on it does not require knowing the user's location. We can simply render a map for a given coordinate region and decorate it with annotations from the article. To put it plainly, does looking up map data about Egypt tell Apple that I'm Egypt? Second, and most importantly, we're already giving Apple the user's location for the Nearby feature. If we wanted to show the user's location, we could simply ask for it. > > Thus we thought we might rather use OpenStreetMap data: If you cache the > tiles on a proxy operated by Wikimedia, then nobody's privacy will be > harmed.

We can add a lot of user value with other features, and in this case simply prompt the user with an "Open With..." dialog to view it in an app of their choice. This shouldn't be necessary, as we can render maps in the Wikipedia app without requiring user location. > > Best, Ulf > > > On 20/03/15 15:38, Brian Gerstle wrote: > > > Adding a native map view to display nearby locations on a map sounds > > like a great feature!
