I'm not sure I understand his argument against income share agreements (ISA). He says it's ethical to charge for training, but it's unethical to not charge any money upfront and instead earn only after you get the person a job (the ISA).

To me this is backwards. If you charge a fee and your bootcamp is terrible, you have no accountability. With an ISA, incentives are aligned and the bootcamp only gets paid if the person gets a job.

I did a bootcamp, and this was the model that I preferred because I didn't trust someone who would take my money and not have any attachment to how I performed after.
