And this is actually a terrible thing. Fortunately my school did this stuff with the Python stack, however the situation is similar to MS Office - it is taught in schools (general education I mean) and so people struggle with e.g. LibreOffice. However I have to agree that the UI of Mathematica is superb. Jupyter Notebook is a nice free alternative, but its recent development (Jupyter Lab) seemed very "ideish" and got me scared (do not get me wrong, it looks pretty slick and must have been complicated to engineer - but for me the nice thing about the notebook was that it is _not_ an IDE like Netbeans, Eclipse, QT-Creator - i.e. the classic ide UI that is separated into editor, file-viewer, shell and something like variable inspector). But this is a different story.
