Kudos to the BBC for increasing awareness of this issue with non-technical device users, who will need manufacturers to implement bedtime mode as a factory-installed feature.

Previous industries have sold products with negative health impacts, with changes eventually coming from consumer pushback, government regulation and/or class-action lawsuits.

There must be at least one mainstream device manufacturer who has a large advertising budget and can take a leadership position by implementing bedtime mode and advertising the health benefits.
