Thanks to all my viewers.
Explanation: this happened because my Haskell video which got big had only three links in the description with no explanation and the links were to Amazon with the search queries shown in this video. Enough people clicked on them that the Amazon brain thought that people all around the world were searching for those products in combination. Search engine optimization resulted and Amazon can't tell the difference between real life and my imagination.
