Facebook Rolls Out News Feed Change That Blocks Watchdogs from Gathering Data – The Markup:

The Markup has found evidence that Facebook is adding changes to its website code that foils automated data collection of news feed posts—a technique that groups like NYU’s Ad Observatory, The Markup, and other researchers and journalists use to audit what’s happening on the platform on a large scale.

The changes, which attach junk code to HTML features meant to improve accessibility for visually impaired users, also impact browser-based ad blocking services on the platform. The new code risks damaging the user experience for people who are visually impaired, a group that has struggled to use the platform in the past.
