If you're into maps and this kind of thing, I highly recommend checking out LocalWiki (https://localwiki.org) too!
The implementation  has various components including:
* Kartotherian : a server capable of providing map tiles in vector (pbf) or raster (png) formats, as well as static map snapshots of any size for a given location.
* Tilerator : a distributed backend tile generation service with a jobque
* A flexible sources  system to set up the needed storage and processing pipeline
Granted that for practicality, you probably also want a mode that makes the labels more useful for a reader that may not understand every writing system, but as a default (when the user doesn't express a language preference), there's something very satisfying about this method of presentation...
In my mind it reflects Wikipedia's aspirations of being a useful tool for the whole world....
I understand your viewpoint, and think it's noble. But you might want to tweak your parenthetical comment. In practice, I and most others do express a default language preference, which is sent as part of the browser's HTTP request. In my case it's:
However, in this specific case I agree with the parent commenter. While the preferred language should affect the UI so you can interact with the map, I feel like in this case translating the content right away could take away from the experience and is not necessarily what the language flag should mean. It shouldn't be more than a click away, though.
However, I think you've misinterpreted the OP's comment and my response.
The OP likes the choice of native language for geographical names in a given country. You and I agree. The OP parenthetically notes that the reason is because the user has not expressed a language preference. I pointed out that the browser/user-agent actually does give a preference, which the server ignores.
It is this parenthetical logic I disagree with, not the result.
This can be complicated - imagine a wiki page about Paris France, translated into 40 or so languages each with their own high performant, cached map served from the same system. Wikimedia maps will be beyond awesome in a few years!
There are actually already ways to browse Commons images on a map, but they need significant work. For example, the tile at  depicts an area with easily 20 geotagged Commons images, but, inexplicably, none of them are shown until you zoom in another level. Or, zoom out to see the entire state, only to see Massachusetts shown as completely lacking any geotagged Commons images .
There is a ton of potential for awesome applications involving geotagged images and geographic maps. I'm glad to see the Wikimedia Foundation stepping up its investment here.
Including the development setup
The data quality is a bit weird, as if it doesn't know what things to highlight. But I'm sure this will improve over time.
Ok folks, let's look at this properly - you are going to get my donation this time round, and in five years google will look worried and in ten the goto mapping solution will be a free Wikipedia service.
Open always wins in the end.
But it seems to me that the designation of green space is off.
Kew Gardens comes out as a built-up area: https://maps.wikimedia.org/#16/51.4778/-0.2975
There are some pretty bad errors on tile boundaries, though:
Scripts are also all over the place. Japan is Japanese only, China is Chinese only, India is English, Bangladesh is Bengali, Pakistan is partly Urdu and English, the Arab countries are totally inconsistent...
Also, I would think national capitals should be included where possible.
Alas, it's an early beta.

Colloquially, "population" refers to either the metropolitan area population or the CSA population, or something in between. But since different countries have different concepts and definitions for "metro area", it can't be relied on for a global map. The only thing remotely portable in this case is "how many people live within the city limits". And by that measure, San Jose is indeed bigger than San Francisco. San Francisco doesn't even get a mention because its population within city limits is below one million - the cut-off line.
Placing labels on a map is quite a hard problem, especially when certain tiles are refreshed.
Some things would benefit from more contrast, but as it happens, almost all map services would.
Looking at the title of this submission, I hoped that it would offer this. However, it seems it does not. Does anybody know if it ever will?

Creative Commons, they have an API if you want to consume the data.
This sort of behavior you're demonstrating is exactly what contributed to recent Ukraine troubles.
P. S. In Italy, cities in Sudtirol - Alto Adige marked in both German and Italian. That's responsible behavior if you want examples.
> marked in both German and Italian.
It's not as simple as "they just now got attacked and now their signs have all been changed".
Crimea and its people have had linguistic/social/cultural/economic ties to Russia/USSR for a lot longer than merely the recent conflict....
There is a lot of shared history around the world, like Alsace-Lorraine, for example. Strangely enough Germany doesn't invade France for some reason...

Your example shows the exact same property. :-)
