Did you know only a tiny percentage of your posts are being seen by those who've "LIKED" you?
It's always been like that.
It has to be. Otherwise it would be unusable. 'Liking' something or being 'Friends' doesn't mean:
"Put every single excreta of information from their feed onto my screen no matter if it's the kind of thing I normally ignore."
Imagine if it was truly like that. If I have 500 acquaintances/items that I'm a friend/fan of .. then everytime I connect to Facebook I'd be drowned with 500 messages!
It would be rapidly unusable.
The part you quoted is the way it *SHOULD* be.
If I interact with someone then more of their feed goes to my screen.
It's a feature of the system - not a fault.
If marketers want to use Facebook to reach an audience then they need to interact with the audience ... not simply dump crap into the stream and be horrified that Facebook in conspiring to hide it!

(eg: Since I often click the links to DClary's comic when it appears in my Facebook post, Facebook does the smart thing and keep DClary's posts visible in my stream ... but someone else who posts stuff that doesn't interest me much gets less visibility. It's a good system.)
