> I really feel like "grab" is quite condescending to a company (Samsung) that provides services at scale (upon/after consent) to help you.. "be better" (simplified..), with direct customization and tailoring.

The headline as described sounds to me like they're violating GDPR by tying to force "consent" for a not-strictly-necessary-for-functionality use of health data. The European Data Protection Board has repeatedly stated that consent is (generally) not considered to be "freely given" if there is a significant detriment for refusing it or if the user has no genuine choice.

Note however that caveat: as described. There may be some more details which make this not unlawful. Also, actually deleting your data if you don't consent is the kind of thing GDPR requires.
