I'm not sure how Apple came to the conclusion Fortnite's popularity is "on the wane" considering just four months ago the game was 100M registered users versus the prior year.
For reasons having nothing to do with Epic’s claims against Apple, Fortnite’s popularity is on the wane. By July 2020, interest in Fortnite had decreased by nearly 70% as compared to October 2019. This lawsuit (and the front-page headlines it has generated) appears to be part of a marketing campaign designed to reinvigorate interest in Fortnite.
