An anonymous reader points us to a link on Quartz: On April 28, 2003, Apple started up a revolution. Enter the iTunes Music Store, unveiled with a proud flourish by a beaming Steve Jobs. It was a digital jukebox, a music distribution game-changer, a record store to end all record stores -- and it did, in fact, kill off a great number of those. [...] For 13 years -- 15 if you count the two years the program was just a file-storing service -- users have grumbled loudly about iTunes' unwieldy interface, its bloated features, its inability to simply get better. [...] Instead of trying to streamline the service over the years, Apple has opted to stuff an overwhelming number of new features -- movies, television shows, podcasts, mobile apps, and most recently, Apple Music -- into it.The report mentions the following issues with iTunes: space-sucking size, slowness, ugliness, bloatware, lack of online or social integration, a wonky back-end, music isn't even its priority. Marco Arment, who is best known for co-founding Tumblr, and creating Instapaper app, noted some development-end issues with iTunes in 2015. He wrote: [...] 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.
