Edit:
This [1] blog post loosely explains it. Pave, which is one of the "lenders" has the following terms:
$3,000 - $25,000 6.97% to 27.10% APR 2 - 3 Year Terms No Prepayment Penalty

20k from parents, family and friends before even turning to loans isn't terribly difficult to get if they're all convinced with you that this is your shot at a 100k+ salary and becoming self-sufficient.
So, you think they should just blatantly lie about what their program is?
It isn't a degree of any kind, or anything even approaching a degree.
It is a bootcamp, and people should take it exactly as seriously as the name implies.
Obviously not. My point is that the term used is too trendy. Calling it something more serious might prove more useful in the long term. Maybe even turning into something that is an actual technical degree with proper accreditation.
Furthermore, most people going through these bootcamps are doing it for a career transition. It's nontrivial but totally doable to save $20k for someone working.
