I could argue it's their responsibility because one of Apple's focuses as a company is health/health care. As a Pebble watch user who moved to an Apple Watch (after Pebble got bought out by Fitbit in 2017), I was amazed they didn't have any sleep tracking functionality. It's not a make or break feature, but as someone with a history of sleeping issue's, I really valued Pebble's tracking feature. If Apple is going to continue pushing Apple devices as the place to go for tracking and managing your health information, they will be seen as responsible for adding features users want.
