Anyone who seriously considers this doesn't know how much cheaper alternatives are.
You can graduate with an associates from a community college pretty much anywhere in the country (United States) for $5000. If you're so broke you'd need an income sharing agreement you likely qualify for a Pell Grant so really your associate's would be free.
Let's say you do poorly and can only get into the easiest public university in your state. Using California as an example, UC Merced is about $15K a year. So it would cost you $35K to get a legit bachelors in computer science from UC Merced vs. $70K from a no name. The only way Make School would be cheaper is if 20% of the sum if your income for 5 years is less than $35K. Needless to say that's unlikely.
EDIT: And this is to say nothing of the fact that you can actually take other classes other than computer science and live a more well rounded life.
