It is if you quit your job with living expenses for the timeline they give and then the timeline extends significantly. I’d be really curious to see how much they warn people upfront that the timelines may get extended and how much flexibility they demand from the students (IE if you get a part time job waiting tables to pay your rent while you’re there an extra 6 months do they get angry when you occasionally need to scrub a flight for scheduling?)

Theres not enough info imo. This could either be really whiney people with no clue how this industry works or they could have some legitimate grievances depending on how the company is running it.
