"But the coding boot-camp field now faces a sobering moment, as two large schools have announced plans to shut down this year — despite backing by major for-profit education companies, Kaplan and the Apollo Education Group, the parent of the University of Phoenix."

Not sure "despite" is the right phrasing here. I'm a DBC grad from about three years ago, and I know DBC had various issues, but I do suspect that there was pressure from Kaplan to expand rapidly, crank prices, and decrease the quality of the education (because that's how Kaplan made their money everywhere else they've been profitable). Kaplan bought them right before my cohort started, and there was serious concern even then that it was a bad omen. I think a lot of startups in general would do well with less pressure for rapid growth, and I suspect that the bootcamp market is much the same.
