>Doesn't this already happen to some extent, with content being classified into advertiser-friendly bins and people's feeds being populated primarily by top content from within the bins the algorithm deems they have an interest in?

The distinction I think would be with publicly disclosable algorithms, you would at least know why you were receiving a particular thing and have the option to not subscribe to that particular algorithm. Ideally such things would be properly, open source. Once public, algorithms are subject to gaming. Open source provides the many eyes and feedback required to stay ahead of the bad actors.
