Well, not everybody has a taste for abstract art, it is understandable.
But did you see his actual photostream (beyond the article)? Like [0], which is at least interesting in its similarity to some crude computer graphics experiment.
Regarding the photography of Wouter Rietberg, there is probably a certain beauty which can touch and can be related to a specific cultural background (maybe an heritage from the Bauhaus design). Everyone is influenced and maybe your perspective of beauty is composed from your own cultural heritage.
On a personal level, I find the work of Wouter Rietberg very dense but towards this too perfect or describing too-polished structure of the world. I'm missing a bit the human imprint or decision to make the photography more natural. It doesn't mean it's ugly or not beautiful, it's just I don't feel my sense of beauty being touched by this photographic approach which looks a bit systematic to my eyes. I'm sure many photographer or viewer might be touched by this systematic approach.
Maybe we're just all blind due to our own perceptions.
