To be fair, Apple does this too to some extent. However, given their most recent commercial re privacy and all of their public statements on the topic, I don't expect them to exploit it for profit quite so shamelessly.
Privacy as current corporate strategy is better than nothing, but it's not really good enough when you're talking about health data or other personal data that will still be highly sensitive for many 30-40 years on from now, when the entire board and leadership of the company and market will have changed in unpredictable ways. There's no true solution to long term uncertainty other than confirmed zero knowledge software and/or regulation.
In Apple-land, health data is synced to the cloud, but encrypted such that Apple doesn’t hold the keys in escrow; they’re peer-to-peer synced between your devices.
Similar impact from a privacy perspective (assuming crypto is unbreakable), but the data certainly is synced.
True, and to the extent they would exploit it, this basically amounts to providing a good customer experience (b/c Health information is useful) so that you continue to buy into the ecosystem.
