Not to worry, your "friends" and/or "groups" are valuable to them as well, probably even more so than any "posts" or "updates" from you would be - those exist solely to trick users into seeing there is value in being on FB, but are otherwise just cluttering up FB's data stores.

Yup, I'm under no illusion I've somehow "beaten" Facebook. They certainly like showing me "Sponsored" posts and loads of ads.
