It’s not. With RSS you are in charge, as you select exactly which feeds you subscribe to and see everything from those feeds. Facebook hides posts from things you subscribed to and shows you stuff you didn’t subscribe to, to keep you hooked.
FB does come with lots of strings attached. We're all aware of that. I'm just suggesting that, with some effort of unfollowing and blocking, it can be useful.
I still use RSS, but sadly, that's not where I find news from local music school or running group. Could it end up differently if FB didn't show up? Quite possibly.
Never seen that myself. Unless you mean video.
