Yeah she's being diplomatic for sure. Dexcom plays ball and is also the most successful of the CGMs, so you would think that others would follow their lead and write their data to apple health. Most companies keep their data thinking its going lead to some unspecified profits down the line but then never really do anything with it.

I still don't understand why they put a 3-hour delay on writing to Apple Health though. Any chance you have context on the why behind it?

I can't think of any reason why they would do that other than specifically to prevent looping.
