This is a fair point, but most vocational programs last years not months, so that is where the analogy breaks down here. I think "vocational" code schools offering 2-year degrees would be very, very attractive as an alternative to a traditional CS degree (both for students and hiring managers), but that's not what we're looking at.
According to a quick Google search, the average program length for these boot camps in 2015 was 11 weeks. That is on par with a single semester at a university. Even if you take a heavy course load of only practical CS courses, one semester is not nearly enough to prepare someone fully for a full-time dev position at top-tier companies. Sure, they may be able to answer the interview questions...but then what? I'm pretty skeptical of this trend and don't see it ending well for most of the boot camp graduates or companies who hire a large number of them.
