Google's default linking of phone numbers across multiple signed-in accounts removes a privacy boundary consumers relied on to keep their digital identities separate. A single phone number now functions as a master key connecting browsing history, location data, and behavioral profiles across accounts users thought were isolated. This gives Google a unified consumer profile while reducing friction if users want to maintain account separation elsewhere. The move reflects Google's business model dependency on comprehensive user tracking and shows how tech platforms continue to narrow consumer choice on data architecture in ways that are simple to implement but hard for users to discover and reverse.
