I don't use many content recommendation systems, so maybe this isn't typical, but youtube's is very good at what it does. It knows I like videos about trains and ships, and suggests virtually nothing else to me. It doesn't need to guess at my motivation for liking trains, all it needs to do is give me train videos.
I think these systems are what you make out of them. If you click trashy content, it'll give you trashy content. If you click politically edgy content, you'll get more of that. If you only click on trains, you'll only get trains. Maybe people who complain about these systems have a totally different experience than me, or maybe they don't like what they see when a content recommendation engine holds up a mirror.
As for their perverse incentives and profit motive... if they're bad at anything, it's getting ad views from me.
