It is insecurity. Some people aren't that self directing and can't navigate the quantity of information with confidence. These people also tend to be learning for money/career, not fun. Fun-directed learning self generates its reward, so it is easier to do it with confidence. Personally, the "promise of a job" marketing betrays the motivation of the students. Not that the motivation is bad, but it isn't how many self-directed learners get their kicks.
