I can see how each public company makes money and can examine their technical decisions. I’ve been working in wearables and healthcare, for instance, since 2010. Fitbit sends all data to the cloud then updates your data in your app. Not a huge deal and provides nice API opportunities. But as soon as Google takes over that data explicitly, I expect it will be used to advertise to me, despite the assurances to the contrary on the acquisition.
By contrast, Apple chose to develop a strong privacy model for health data on the Phone. They certainly didn’t need to and could have readily chosen the same cloud-first implementation. But they didn’t. And the APIs are harder to work with as a consequence. I respect and appreciate those decisions and so I buy their products more. You may choose differently.
