As someone said, minority languages do benefit from Wikipedia. Or sometimes.

The Broad Scots one was mangled by someone who couldn't even speak it and that made international news.

The Scottish Gaelic one got taken over by a German guy. It seems something similar has happened with Greenlandic. A learner from outside Greenland has taken it over, and by his own admission deleted vast numbers of articles.

Here is what they say: "When I became admin, there were around 1500 articles, most of them consisting only of a few words or completely unintelligible. I deleted most of them some years ago, so now there are only around 250 articles left, which more or less consist of some sentences, which seem to be written by Greenlanders."

I have no doubt that deleting hundreds of articles "of a few words" probably drove people away from the site. In fact, a native speaker of Greenlandic points out further down the discussion that important articles were being deleted and not just machine translated ones.

The deletion discussion reminds me of why partly I took against Wikipedia. Greenlandic is a language used in schools and government, so you would think someone in either of those fields would have encouraged people to write a few more articles. Unless it was all mired in bureaucracy.
