Apple – which advertises Safari as “incredibly private” – evidently has undermined privacy among European Union Safari users through a marketplace-kit: URI scheme that potentially allows approved third-party app stores to follow those users around the web.
I don’t see Apple deliberately sabotaging their platform to maliciously comply and blame the regulation for making users less safe. This was probably an error caused by quick development to comply within a set timeline that will be resolved in the future through software changes.
