A look at Facebook Groups, used by two thirds of Facebook's MAUs and a company focus since 2017, which make leaving the platform especially difficult
Facebook invested heavily in the one feature it knew people couldn't leave behind: Their groups — Before the pandemic, Andrea Norrington barely checked Facebook.

Fowler / @geoffreyfowler : This illustration with @heatherkelly's piece today about how hard it is to quit Facebook is very 2020 mood. Saveeeemeeeeeeeeeeee .... https://www.washingtonpost.com/ ... https://twitter.com/... Kaitlin Pike / @kcpike : This is me. I'm in a few (and manage) several hundred person groups, and “just moving” isn't an option right now. And I definitely looked into it. It's like being stuck in a dying town because that's the only place your support network can live. https://twitter.com/... Venkat Ananth / @venkatananth : “Of the 2.74 billion users around the world who check Facebook at least once a month, two-thirds of them use the Groups feature at least once a month” https://www.washingtonpost.com/ ... Olivier Amar / @olivier_amar : Fact. It's basically the only reason I go to FB. The school and neighborhood groups. That being said, going on two years without the mobile app. https://twitter.com/... Heather Kelly / @heatherkelly : I talked to people who want to leave Facebook but are staying for their groups. Whether it's support communities for shared illnesses, or that one where people are angry at corn, groups aren't easy to move off Facebook. https://www.washingtonpost.com/ ...
Context & Ripple Effects
The Washington Post's piece lands at the intersection of two threads in the coverage: Facebook's deliberate push to make Groups a company focus since 2017, and the pandemic-era influx of millennial and Gen Z users who arrived specifically for unemployment support and job-search groups rather than the News Feed. Groups had already been repositioned as the safer corner of the platform — the 2019 privacy overhaul collapsed the settings to public and private, building on earlier reporting that private groups shield communities from trolls.
What the Post adds is the retention angle: with two-thirds of monthly actives using Groups, the feature functions as Facebook's exit barrier — Andrea Norrington barely opened the app before her group pulled her back in. That matters against the backdrop of internal research showing 12.5% of survey participants reporting compulsive use that hurt their lives, and leadership having shelved research into the platform's polarizing effect rather than applying it to products.
First-order effects
- For users like Norrington, quitting Facebook now means abandoning the community, not just the feed — the group roster, not personal content, is what they cannot take with them.
- For Facebook, Groups converts even low-engagement members into monthly actives, propping up the MAU base that advertising is sold against.
Second-order effects
- Rivals face a graph problem, not a features problem: any competitor can copy a feed, but recreating hundreds of millions of embedded group relationships is the actual switching cost Facebook built.
- Group admins become de facto infrastructure — Facebook's 2019 privacy simplification forced thousands of communities to re-map their settings overnight, showing how much governance power sits with the platform rather than the members.
Third-order effects
- If community lock-in keeps outperforming content as a retention mechanism, the endgame is platforms competing on whose groups are portable — or regulators treating switching costs as the antitrust issue rather than market share.
- The pattern also contains its own counter-current: reporting on users retreating into closed groups as public feeds fill with influencer content suggests demand for small private spaces may eventually migrate off mega-platforms entirely.
The trend: Social platforms are shifting from competing on feeds and content to competing on community lock-in, making the group graph — not the algorithm — the real moat.
