As a consumer, I prefer Apple building all of that into the OS because I assume any other business will sell out at some point. I recall quite a bit of bad publicity when the menstruation trackers were found to be selling data.
But seriously, what a great app that is sorely missed now.
As a Dark Sky fan for years, I understand losing something you've gotten used to. But Apple Weather is great for most people, and die-hards like me can move to apps like Weathergraph.
