Ask HN: Why does academia still publish in for-profit journals?

As a teenager who has just graduated high school, and is evaluating entering the university research scene, this is a question that has stuck in my mind for a while. I have seen countless articles here, and elsewhere, explaining why for-profit journals for scientific papers is a bad idea... Why is the problem still so prolific?

Is it a result of the interests of the researchers not aligning with the decision-makers, an issue with lobbying, or something else?
