There's a huge difference between using the prepackaged black box solution for the sake of efficiency (as everyone should), and not caring at all to understand even the basics of how it actually works. The later usually leaves one too intimidated to change anything and vulnerable to any unexpected situation. And things break all the time, you need to debug problems with tools and servers and run into all kinds of exotic issues. I once worked with a front-end dev who would restart his machine when he needed to reset a local web server, because "it's not his job" to learn a bit about using the command prompt. For me that is plain crazy attitude and it's not that rare...
