Does Apple give that choice?
Pretty sure on my iPhone I can run:
- Maps: Google Maps, Apple Maps, Waze
- Music: Spotify, Apple Music, Pandora, Amazon Music, Google Play Music
- Documents: MS Word, Pages, Google Docs
- Mail: Gmail, Apple Mail, Outlook
- Messaging: WhatsApp, iMessage, Signal, Facebook Messenger (and so many more)
- etc... etc...
Lots of choice. Sure some things are a bit more locked down when securing user data comes into play (e.g.: iMessage, FaceTime, Health -- and how things interact with Apple Watch), but for the most part those are exceptions, not the rule.
Right now these manufacturers are specifically disallowing screen casting from your phone. This requires ZERO access to sensitive data on the driver. It requires ZERO privileged access to the Car's functions (exception: CarPlay Ultra does not want some info), and it does NOT remove the default car infotainment software -- in fact it makes it fully accessible with an app icon to switch back at any time.
This would be like Apple refusing to allow Google Maps on the iPhone because Apple wanted you to use their maps software. If these CEO's prefer their infotainment crapware, then they are free to run it -- but don't force every customer to run it. My solution to that is to NOT be their customer.
