Did you read the article? The problem is not just the fee (insanely high for a bootcamp), but that graduates are hired out to companies and paid rates that sound much lower than market rates, which most likely they are charging the companies a higher rate for. And if they refuse they have to pay the fee.

Your college owns you for 2-3 years after graduation and can hire you out and decide where you live and work and at what rate?

Sounds a lot like indentured servitude.
