Not sure about other states, but California has super low cost junior colleges with CS classes. It seems like the Austen’s of the world would advise people to start there and see how they do rather than jump into a $50k commitment. The other baffling thing about Lambda was that companies had to pay Lambda to recruit their students.

Additionally, at Cuesta the first month of bus rides is free, and the bus tickets themselves can be purchased at ~50 bucks a month. It's not too hard to find some roommates in town and get some cheap rent, too.
In return, you can get a curriculum that closely follows that of Cal Poly (often with teachers who teach at both institutions!), and a fairly successful transfer program.
Of course once you get into the university the costs are much higher, but you don't have mandatory dorms anymore, but you did two years on the cheap, and when you combine financial aid, scholarships, and federal student loans it's not ridiculous to have $20k or less in debt by the time you graduate. With a decent job in tech, that can be paid off in under a year.
Unfortunately, the job market is really tough right now for fresh grads, so that last part is where this falls apart, but I'd wager it's relatively easier for someone with a proper four-year degree than someone with a bootcamp credential.
