From the Wall Street Journal's "Google Plans to Curtail Cross-App Tracking on Android Phones" posted Wednesday:
Google plans to adopt new privacy restrictions to curtail tracking across apps on Android smartphones, following Apple Inc. in putting restraints on an advertising industry that has covertly collected data across billions of mobile devices.
Google’s plans for Android could hasten an end to more than a decade of advertising practices across smartphones in which companies including Meta Platforms Inc.’s Facebook layered their code into hundreds of thousands of apps to track consumer behavior.
Apple’s changes, which went into effect last year, have already upended the digital-ad industry and contributed to a wipeout of more than $300 billion from Meta’s market value...
The Alphabet Inc. unit said it plans to keep supporting current smartphone identifiers for at least the next two years and to give the industry substantial notice before any changes. It said it plans to work with the industry to develop the replacements.
My take: A one-two punch to Meta's business model.
