Thanks for being inquisitive.
It's easy to look at this as giving education to those who wouldn't get it otherwise.
But there is a dark side: https://medium.com/@kevgardner83/the-true-cost-of-income-sha...
> The average up-front tuition amount for coding bootcamps is $10,000 to $15,000, according to Course Report, which collects data and reviews on coding bootcamps. The idea to not pay thousands of dollars at the start of the program may be attractive. But, let’s say you agree to an ISA. And after completing the a coding bootcamp, you’re hired with a salary of $60,000 a year. If you pay 20 percent of your salary for four years, you’ll end up paying $48,000. That’s more than four times the average cost for an up-front payment to a coding bootcamp.
It's basically charging those with the least money more tuition. It would be fine if they capped it at the tuition price or even a nominal interest rate, but some programs make 400% more from students that can't afford upfront tuition.
It's fine if you want to charge everyone in your bootcamp under the ISA model, but if you offer a $10k tuition and a $40k ISA you're basically offering the same product at vastly different prices to two different economic groups.
