RSS is an older web standard that lets people subscribe to content feeds without algorithmic filtering — the EFF is highlighting it as a practical tool to reduce dependence on platform-controlled feeds. This matters because major platforms algorithmically control what content users see, which shapes what information reaches people and can amplify engagement-driving content over accuracy. The broader context is a documented trend of platforms using algorithmic sorting to maximize engagement (and advertising revenue) rather than user choice — RSS puts control back in the user's hands by letting them aggregate feeds directly.
