They kept changing stuff, breaking my work flow, with every change it felt like there was more friction to listen to the music and podcasts I wanted, and less friction to listen to algorithmically selected slop I didn't want to listen to. Eventually I just said fuck it. I don't need this source of stress and frustration in my life. I've never looked back.
I'm on youtube music now. In many ways it's a worse product, but it at least stays the same and doesn't keep trying to make me change my listening behavior.
I suspect Spotify's problem is that they have (or had) too many developers, so you get this pressure to look busy "improving" the product, with endless lateral change as a result instead.
For newer Apple apps, sometimes the keyboard shortcuts simply don't exist. I believe part of the problem here is the deprecation of AppleScript, which means there's no incentive to spend time on consistency, and the other part has to do with organizational indifference towards all the wonderful UX innovations from the past.
What Apple has successfully accomplished, in collaboration with other 'big tech' companies is drastically reducing user expectations from their software. I wouldn't completely blame the AppStore's forced race to the bottom for this alone. There is still a huge market for tasteful apps that cost more (even sometimes with obnoxious subscriptions), but if even Apple isn't leading by example, why waste time on it if you could just build another simple note-taking app.
