Based on the original article the guy left a trail of destruction. Clearly has no idea how to properly cut or maintain hedges.

The original article mentions at least one address, and based on Streetview from two years ago I don’t get the impression that these people don’t maintain their hedges at all. There are clear signs of work having been done either by people who have been doing so for a while or by some kind of landscaping company.

To me, this looks more like a “bored, grumpy old man destroys peoples’ hedges” story.
