Depends on the definition of "work". There's plenty of people I had on Facebook that I no longer talk to because I don't use Facebook. To be clear, my Facebook still exists. It's there to face tank all the family photos my MIL shares. That's the only reason they account still exists at all.

That's technically working for me.

But lots of people are just addicted and Facebook or insta or messenger scratches an itch for them.
