IMO, this is the essence of why ISAs have become so scammy.
ISA-based bootcamps are doing a fantastic job of competing against the perceived cost of a college education. We've all seen news headlines about how private college tuition is reaching $200K. What most people miss is that almost nobody pays full price for college. They have a high headline number for the wealthiest families, but virtually everyone else pays a fraction of this cost or some times nothing at all.
People see the "$30K" price tag for Lambda School and other programs and assume it's a steal, yet most in-state tuitions are in the same range and provide substantially more education.
I've also been completely stunned by how bad some of these programs are. I took the bait about Lambda School back when PG was promoting it all over Twitter, but it has been a terrible disappointment for the small handful of bright students I've known who went through it. Maybe it's changed, but at the time it felt like they were paying $30K of future earnings to have an inexperienced person point them to simple tutorials that they could have found by themselves online. They were basically paying for the certificate that said they completed the program, which is ironically the stereotype that people were using for 4-year colleges at the time.
