I honestly just like many aspects of the UI, so I try and recreate those. The only thing that's actually just copying apple for no good reason is setting the icon of logo menu to Apple, and I mostly do it to see others' puzzled faces.
To be honest, I've never owned an apple device: only Android phones and windows (with Linux immediately installed) laptops. However, I kind of like the icon aesthetic the most out of all the ones I've tried.
The theme also grew on me during my Gnome days, so yup, these days I pretend my device is an apple from a cosmetic sense 😂
