I will concede that the YouTube Music app started (and might still be) worse than GPM was in the end. But I'm not sure it could be considered enshittification. Yeah, the YTM app itself was kinda shit, especially at first - but they didn't make the service materially worse and charge more for features they took away. They didn't jack up the price to coincide with the "new" service, they just consolidated the two separate services into one. They didn't introduce ads. They didn't silently take down a ton of the music offered and leave the price the same - they still have the same 100M tracks as the other guys, and you ONLY get music from those other services.

I agree and get where you're coming from on this example - but I think people use the term enshittification more broadly than it's actual definition, and in my opinion this doesn't fit.
