Brave said it would block the script by default. As of August 25, AliExpress has not made an official statement.","whyItMatters":"A major browser blocking a script by default shows a concrete response to covert device tracking, while the silence from AliExpress leaves the claim unanswered.","webCardHtml":"\u003cp\u003eThe discovery began when a user noticed that opening AliExpress on a PC caused Bluetooth headphone audio to stop.

The script still executes until users update their browser, and AliExpress has not responded. The real test is whether the platform changes its tracking method or doubles down.","newsletterBlurb":"Brave accused AliExpress of tracking users through an inaudible audio file that creates a device fingerprint without cookies. The browser now blocks the script by default.
