How they arrived at that design decision I can only wonder. Probably not even malicious, just taking the easiest path. And now they even managed to get their app dropped from Apple's app store. I understand people don't want to tinker with their setup, but relying on closed systems like Apple's and Abbott's risks exactly such scenarios.
I'd like to kick Abbott entirely. And I keep trying to switch to competitor Dexcom, who are a little bit more open. But their hardware just doesn't work as well for me.
So far none of the seven Dexcom G7 sensors I tried made it to ten days. Three came off within one day, one was a dud, one failed from the start, and two made it to around day six before becoming unreliable and failing eventually.
My experience last year with G6 was that they'd start getting unreliable after day six. At least they stayed on :-/
So maybe I react with inflammation or something to their sensor probe. They just don't work for me. And the glue in the G7 doesn't stick either, which is a new problem.
So Abbott it is, luckily without their patronizing app.
And what happens on the server probably doesn't need certification.
They do however go out of their way to make it hard for third parties. They encrypt their app and run integrity checks to detect patches. Now writing this again makes me feel like they purposefully block third parties, not just ignore them.
