(Might be a problem of that university, still ...)
In our department, about 20% reach a master. Sure that's more well rounded than a random bunch of courses, but it should be possible to even surpass the rigid choices of a lot of universities. I have no numbers for MOOCs at hand. If I had to guess: more like a gym: a lot of members, an order of magnitude less finishers?
I personally prefer the interaction on campus. But I dislike the outdated content of a lot of professors -- I'm not arguing about basics that are still relevant, I mean their /SoTA/ from 5-15y ago.
But MOOCs and other purely online options just didn't result in any meaningful certification especially outside of a connection to established universities. And, given that, people/companies weren't interested in paying significant bucks for them.
It was probably a useful experiment. Just not a very successful one. And once the experiment faltered, schools/professors became less interested in putting money and energy into it.
All the evidence is that most of the students/potential students who weren't already motivated to pursuing independent learning didn't really connect to all this online material.
While these Udemy is fine for building up CV bullet point skills, I have never felt that these tutorial based job training courses, designed to teach you framework N+1 were as useful as more fundamentaly and in depth courses that lead you to understand how things really work.
That's what Udemy was from the start. If you want depth, it was always Coursera.
