Not just Pages, but I've read this is also coming to any user who at some point in the past clicked the prompt to turn their account into a "pro" one. I did it long ago, just to see what info it would give me; then found little of interest, and forgot about it. Since then people have followed me who didn't friend me. Now, I can revert to a non-pro account (gaining ability to post more than 2 links) but I'd lose all the non-friend followers. Whatever. It's amazing how much junk FB is now. My feed is mostly crap from people/pages I don't follow and have no interest in.
