It's not arguing by authority, it's arguing by counterexample. Robert Henke doesn't represent all musicians, but he is a musician, so it's not possible that Ableton doesn't reflect the perspective of any musician. All the things you mention relate to a certain workflow. It's not my workflow, it's not every musician's workflow. It'd be great if Ableton had good SysEx support, but it's not accurate to say it has a "complete disregard for music" because it doesn't fit your workflow exactly. Ableton is designed to simplify working with repetitive beats. If you don't want any of those, of course it's going to be difficult to use.
