Apple has Seamless Cross-Platform Involvement: The source suggests that Google has deep software involvement within the Apple ecosystem, to the point where it does not feel like a third party. This is contrasted with a specific failure in Apple's own integration, where a synced Google calendar failed to display Father's Day on the Apple lock screen—a "meaningful cue" that the user felt was missing despite the systems being synced. To apples credit, allowing Google to connect really does make iPhone feel more personal because of the custom software and service choices you have either way.
