Disclaimer - taught GA part-time courses (data science)
My heart goes out to those people, and I'm guessing Web Development Immersive students?
I always described GA's programs as a multiplier in that your outcome is going to be weighted by your experience going in. And for the most part I felt GA managed that expectation fairly well for most of its immersive programs - except Web Development.
In WDI I would see students who had no background in CS, design, etc. hoping to go from no experience to a full-stack developer position in 12 weeks. With a broad curriculum that iirc was starting with html/css fundamentals and working through Rails/Node/... maybe Angular? I felt it was giving them a base to start learning on their own, but not enough to immediately start working except for the very-top students (who likely had some sort of helpful background coming in).
I do believe GA is at its core a good organization that wants to see its students succeed (can't say enough good things about the career coaching / placement staff aka "outcomes"). But I can see how with a lot of competition in that space, the sell may have gotten stronger than what the product supports - and that's 100% on GA to address.
