What FB should have done is let users control what is in their feed - give them options to define groups of people and let them view just certain groups in the feed, or split the concepts of liking and following. Instead it seems Facebook is happy to spam users for you if you'll pay for the privilege. Not really good for anyone involved, and not worth it for businesses long term to pay only to be perceived as unwanted spam amongst personal posts.
Facebook does have groups. But yes, what Facebook did was a bait-and-switch: there were likes, which were just biographical information, but then those turned into subscriptions.
