It is a very perverse method to steal user data, fooling regulators and 
operating system designers. On Android phones only, if the facebook or 
instagram app are installed and a session has been opened at some point 
in time. Not clear about WhatsApp/Messenger

     *“Localhost tracking” explained. It could cost Meta 32 billion.*
     You just can't finish off Zuckerberg.

     What happened?

     Meta devised an ingenious system (“localhost tracking”) that 
bypassed Android’s sandbox protections to identify you while browsing on 
your mobile phone — even if you used a VPN, the browser’s incognito 
mode, and refused or deleted cookies in every session.

     Next, we preview what may (and should) become the combined 
sanctioning smackdown of the century, and then we explain — in simple 
terms (because it’s complicated) — what Meta was doing.

     *It smells like record fine spirit*

     Meta faces simultaneous liability under the following regulations, 
listed from least to most severe: GDPR, DSA, and DMA (I’m not even 
including the ePrivacy Directive because it’s laughable).

     GDPR, DMA, and DSA protect different legal interests, so the 
penalties under each can be imposed cumulatively.

     The combined theoretical maximum risk amounts to approximately €32 
billion** (4% + 6% + 10% of Meta’s global annual revenue, which 
surpassed €164 billion in 2024).

     Maximum fines have never before been applied simultaneously, but 
some might say these scoundrels have earned it.
