I do not see a problem with that. All that shows is that those programmers are only familiar with the tool that they use. Remove that tool and they flounder until they learn to use the new set of tools that they have at hand.
What I can imagine and in fact have seen, are programmers who know how to push buttons, right-click, mouse-over, but are lost outside of the IDE. Even something as simple as browsing and editing source is a challenge, let alone compiling, linking, and running a simple test program.
