Adobe got Flash running on Android. It was literally the official solution for DRM video on the platform. It didn't have amazing performance, but it did just about play DRM video and Google didn't really get native Widevine support working for several years. It's certainly a valid reading that Apple knew video providers couldn't stop using DRM (they were contractually required to), and therefore would have to distribute using the App Store rather than the browser to get a DRM solution that worked in the absence of Flash, and therefore Apple could attempt to extract 30% of their revenue.
