Out of curiosity, why do you ask if they are web developers?
Web devs tend to be easily replaceable, so why not hire a bunch of juniors (at a cheap cost) to get the job done? This is what it seems these types of "academies" are targeting anyway. Like "timr" said in this thread: "... a commodity product for a commodity world."
"Suckers" might be a bit strong, but their expectations may suffer a certain misalignment with reality.
Of course, it's possible that those were outliers. The population is clearly non-zero, though.
