Wikipedia can be strange sometimes, in particular the german variant.

Ignoring all other factors, IMO there should be an article about Odin the programming language. Deleting an article about something that exists, is incredibly stupid; not sure why Wikipedia resorts to that. If Wikipdia deems Odin not noteworthy - and I don't really care about Odin myself - then the article could be kept short. That would still be better than deleting it.

Wikipedia started with the goal of a database of literally everything. One could argue that Odin is not relevant because it may not be used by anyone, but then this would need to be an objective argument based on numbers and data, because many other programming languages are used by few people yet are mentioned on Wikipedia. So, that seems to be a stupid decision by those responsible on Wikipedia. CensorshipBros are annoying in general - the english wikipedia is much more open than the german wikipedia by the way.
