"Apple's"?
HEIC is HEVC encoded image in a HEIF container, it's defined in ISO/IEC 23008-12, and was created by the Motion Picture Experts Group.
Further more, it's supported by Windows 10/11, Android 10 and Ubuntu 20.04.
Or did you mean, it's not really supported by browsers other than Safari?
Whose fault is that?

Why, exactly?
Did you also wish for H.264 playback support to "go away" when Safari supported it, but neither Chrome nor Firefox did?
