There’s fairly broad political pressure to regulate large players in online platforms such as Apple and Google. As a result, the EU regulated online platforms. As is often the case, they aren’t stupid, and put more stringent requirements on large players than on smaller ones. So, they have to know which players are smaller and which are larger. They chose to use number of active users as the way to measure whether players are large, with 10% of the population (45 million) a cut-off point. That’s why they require all digital services companies to report # of active users. (Aside: it turns out that Wikipedia is a very large online platform, too.
