Short Reads - The ACM worries that the use of algorithms may lead to the creation of cartels, or nudge consumers towards a purchasing decision that is not in their best interest. Therefore, on 10 December 2020, it published a new policy document (in Dutch) setting out what businesses can expect when the ACM checks their algorithms. On the same day, the ACM also launched a trial with online music library Muziekweb to improve the ACM’s knowledge about the categories of data that are likely to be relevant in such investigations. All signs indicate the ACM’s intention to become more active in this area.
