it's reported
"Apple has scrapped certain health-monitoring technologies from its upcoming Watch, it's reported"
Who is it reported by? two journalists at the WSJ
Who first broke the rumour that the Watch would be able to do all this monitoring? the same journalists at the WSJ last June.
Evidently the WSJ's approach to journalism is to make wild, unsubstantiated claims about a future product before it's been announced. And then, when the final product doesn't fullfill those claims, to then write a story about how the company had to abandon their plans.
