Anyone that has a problem with Facebook and the content they see on it has nobody to blame but themselves. Facebook is what you make it, nothing more, nothing less. You can unfollow/unfriend whoever you want, be it friends, family or public pages if you don't want to see their content. You can block people so they cannot see your content. Hell, you can even stay "friends" with someone, but block what they see and block what stuff of theirs you see, so that technically they're still your "facebook friend" but neither one can see the other's stuff, thereby avoiding confrontation with that crazy aunt at Christmas that wants to know why you "unfriended" her.
