The 8-Bitreports that WebM is a niche video codec that isn't widely used today. Most other browsers supported WebM already with Apple being among the last to add support.
All browsers on iOS do not support WebM since browsers like Chrome and Firefox must use Apple's Safari web engine. There is no current indication of Apple bringing support to iOS, in beta, or otherwise.
