I think you are the one who didn't read the article. The ride was only mentioned in the beginning as the thing that started the cycling shorts use trend.
It goes on to describe how widespread the practice of upskirting is at Oktoberfest in general, and how many workers are having to wear them to avoid being filmed and how patrons are concerned the law doesn't protect sharing film of the wind picking up a skirt and briefly revealing something.
And you got my point exactly. Why are we blamed for people taking upskirt pictures of our underwear or bare bottoms. Just because our skirt wasn't down to our ankles and so tight around our legs we could barely walk or we wore sexy underwear, doesn't mean we were to blame for tempting them as is often the excuse in cultures that don't strictly criminalize and enforce punishment of the practice.
