The most depressing thing about ableton is made obvious in two seconds of messing with that tutorial. A complete disregard for music in the sense of pushing boundaries of time, or doing things that are not tied to any sort of grid, and the sense of music as an emotive form.
So many aspects of music are very annoying or borderline impossible to do in ableton. Yet in all these years, and with so many installations, they just never addressed those issues. Instead they vaguely pretend as if music that would require features they don't have is radically experimental. Which might become true if so many people learn music only through using their software.
Seriously, Ableton. Stop pretending making music is clicking on and off in little boxes. It's embarrassing.

Edited to take out the "art" part and put in a couple of more specific criticisms.
