Porsche has a reasonably priced upgrade path for their head units even in quite old cars which add Carplay. The value is obvious to them - it maintains a high resale value on older vehicles which maintains their higher current sale value.

Something I found interesting when I was hacking my VW to add Carplay (without paying £300) was that a ton of manufacturers in the ~2016 era use the exact same head unit and OS but with a different front fascia, different button layout and a relatively advanced UI skinning system. If you can be bothered you can add e.g. Audi track G-sensors to your VW or use a different skin.
