I'm Jewish so I can give you my point of view, but there are many other people who may feel differently. For me this is simply a troll doing something that he thinks is funny and slightly inconveniences the mods at osm. Calling certain areas "Jewish" is not antisemitic in the way that is in any way dangerous. Here is a joke from Jews about how Teaneck is Jewish [1], nothing antisemitic about that. Here is a joke about Israel being Jewish [2] .

But lets just say that this was antisemitic. So what? Trolls do offensive things online all the time. OSM was properly alerted to it and quickly reverted it.

There were a few other edits by the same person which were a little more extreme and anti-semetic

Oh, well then that might change my opinion. I will try to find a better source when I have some time. I find it stage that the osm letter didn't mention exactly what happened.

> the osm letter didn't mention exactly what happened.

What do you mean? It's quite clear what happened. Someone logged into OSM, they edited the "place node" for New York and changed the name.

That is what I thought, but you replied saying that he made other edits ... What happened? Did he just change the title (not so bad) or did he do something worse?

They changed the name of some other things. Roads in New York being renamed after a certain dictator with a small moustach. That kind of thing.
