I can’t quite understand why people still use Facebook’s services, other than vendor lock-in?

The tool I created, a browser extension called Unfollow Everything, allowed users to delete their News Feed by unfollowing their friends, groups, and pages. The News Feed, as users of Facebook know, is that never-ending page that greets you when you log in. It’s the central hub of Facebook. It’s also a major source of revenue. As a Facebook whistleblower observed on 60 Minutes on Sunday, time spent on the platform translates to ads viewed and clicked on, which in turn translates to billions of dollars for Facebook. The News Feed is the thing that keeps people glued to the platform for hours on end, often on a daily basis; without it, time spent on the network would drop considerably.

Facebook’s behavior isn’t just anti-competitive; it’s anti-consumer. We are being locked into platforms by virtue of their undeniable usefulness, and then prevented from making legitimate choices over how we use them—not just through the squashing of tools like Unfollow Everything, but through the highly manipulative designs and features platforms adopt in the first place. The loser here is the user, and the cost is counted in billions of wasted hours spent on Facebook.
