I have to be honest that I’m not really seeing any major issues here. They _used_ to do something and now they don’t, so he didn’t lie about it. They _have_ had low placement rates and informed their investors, but it’s unclear what the average or common placement rate is and if it’s significantly different from what they claim. And _some_ students didn’t like the curriculum. ¯\_(ツ)_/¯
You also make reference to some internal documents. Perhaps sharing them will help further the story?
