Well, sure, but there's a difference between using Facebook heavily and using Facebook occasionally. It's not a binary. Indeed, you can even use Facebook once in a blue moon. For instance, you can log out on all your devices and set your password to something you've autogenerated but you haven't saved so you have to go through the "forgot password" process.

Facebook wants to be addictive, but it's okay and possible to use it once every two or three months so you can add your great aunt and post holiday photos (so people know you're safe). And by using Facebook less, it takes away some of Mark Zuckerberg's power over you and our society.
