I don’t really see the issue. Minimalism is a sliding scale.
Just because the design goal was for it to be more minimalist than a typical Android/iOS phone doesn’t mean they have to go full-on “NO. It’s only for phonecalls and maybe SMS!”
Playing music isn’t particularly “maximalist”, and WhatsApp certainly isn’t (people in the US need to understand that WhatsApp is basically SMS for most of the world). Maybe maps is, but it’s optional anyway so who cares.
This device looks very cool to me. But there’s no way it won’t cost an absolute fortune, which kills it IMO.
