Complexity in music is often a protection against attacks and critics. It is a perfect shield:
you are able to explain your music like a scientific work with impressing facts and formulas. (nothing from that is audible though). If somebody dislike this music or is just clueless, this person has simply not understood your music and is just not on your level.
The academic circles are satisfied.
If you write a simple and clear peace everybody could attack you: nothing is hided, everything is open and scholars could easily destroy that kind of music with a few words.
Nowadays it is not curious at all to write music which is atonal, complex, experimental etc. - it is safe and comfortable. It is inside the circles where this kind of music is expected. It is the opposite of innovation, it is just keeping the status quo. It is conservative.
