Pretty damning. Let's not forget Tim Cook used the "toxic hellstew" phrase during an Apple keynote in reference to Android. Yes he was quoting someone from ZDNet but he still used it.

But the iTunes Store back-end is a toxic hellstew of unreliability. Everything that touches the iTunes Store has a spotty record for me and almost every Mac owner I know.
And the iTunes app itself is the toxic hellstew. iTunes has an impossible combination of tasks on its plate that cannot be done well. iTunes is the definition of cruft and technical debt. It was an early version of iTunes that demonstrated the first software bugs to Grace Hopper in 1946.
Probably not coincidentally, some of iTunes’ least reliable features are reliant on the iTunes Store back-end, including Genius from forever ago, iTunes Match more recently, and now, Apple Music.
iTunes’ UI design is horrible for similar reasons: not because it has bad designers, but because they’ve been given an impossible task: cramming waytoo much functionality into a single app while also making it look “clean”.
iTunes is designed by the Junk Drawer Method: when enough cruft has built up that somebody tells the team to redesign it, while also adding and heavily promoting these great new features in the UI that are really important to the company’s other interests and are absolutely non-negotiable, the only thing they can really do is hide all of the old complexity in new places.
With the introduction of Apple Music, Apple confusingly introduced a confusing service backed by the iTunes Store that’s confusingly integrated into iTunes and the iOS Music app (don’t even get me started on that) and partially, maybe, mostly replaces the also very confusing and historically unreliable iTunes Match.
So iTunes is a toxic hellstew of technical cruft and a toxic hellstew of UI design, in the middle of a transition between two partly redundant cloud services, both of which are confusing and vague to most people about which songs of theirs are in the cloud, which are safe to delete, and which ones they actually have.
