It becomes harder over time to function in society without a smart phone (I know this because I barely use mine and it usually lives at home but my partner runs her life off hers).
We need laws mandating open and interoperable interfaces and standards for all the things a modern life takes for granted: public transit, banking, digital ID, etc.
Once that's in place, we can start talking about what people are "choosing". Because currently our "choice" is at best between a rock and a hard place (or as we say in my native tongue: between plague and cholera).
Privacy? Just buy Apple (largely an urban legend at this point, but regardless).
Actual ownership? Just buy Android.
Security? Just buy Apple (or Pixel with GrapheneOS).
Repairability? Just buy one of these 4 Android models.
Headphone jack? lol.
