What does the new ISP data-sharing rollback actually change?

Congress shot down the Federal Communications Commission’s internet privacy rules this week, and in doing so, created a world of confusion over what Americans should expect when it comes to online privacy. With the protections gone, no one’s quite sure what to expect — some suspect their browsing habits are going up for sale, while others see no changes coming whatsoever. That uncertainty and confusion is justified: the rules Congress shot down were meant to clarify an existing set of already vague and confusing policies. On some level, it’s being left up to internet service providers, or ISPs, to decide what the rules do and don’t allow them to do. And while none of them are very clear about their intentions, there’s plenty we can suss out based on what we already know. So to cut through the haze, we pulled together everything you need to know about the current state of online privacy rules.
