The support/general overhead wasn't cheap either. When I was there we had a free therapist, mandatory morning yoga, teambuiliding exercises, and stuff like weekly free food, etc.
This might have something to do with their financial issues. You obviously don't need these kinds of amenities to learn how to code a SPA. I'd be put off by them and wonder where my money was going and why.
Answering as a current employee. When these were being phased out to start to lower costs students and graduates reacted strongly that they felt they were a large part of our value. Part of what makes us "us". As another commenter in here pointed out: bootcamps aren't for everyone.
We were up front about these things being part of our program because we want to focus on the human aspects of people as much as technical skills. That meant some people were better suited to join other places, but some people came specifically because of this part of it.
That makes more sense, but didn't people ever raise an eyebrow about a therapist on staff, or requiring yoga? From the outside, the optics of that could be interpreted quite a few ways.
DBC grad here (Chicago 2013). Mandatory morning yoga is not an inherent part of a generic coding bootcamp experience. DBC chose to make yoga classes part of its unique culture, but I doubt all other bootcamps follow suit.
Personally, I wasn't "enraged" by the yoga and I even appreciated the emphasis on mental health, but I don't think yoga was the only way to achieve this and I would have appreciated the chance to opt out.
