Comparing the system Music app which has existed since iOS 1.0 with an optional music streaming service that can be disabled as “equivalently bad” as carrier bloatware pretty much undermines your point entirely.

Honestly where I live, we usually don't buy phones from carriers(as far as I know it's not that common outside US - you guys seem to have outrageously expensive plans due to that), so I'm comparing to what manufacturers install.

Worst I had to deal with was shortcut to OnePlus community forum, which is arguably less offensive than Apple Music, which is often reported to bind to the Bluetooth play button.
