The mistake is thinking that people will choose a car first and let the car manufacturer dictate what phones they can use.
In reality, people are more invested in their phone than their car brand. Tell me I can’t use my phone with your car? Ok, there are plenty of other car choices.
This reminds me of when the balance of power shifted from cell networks to phone makers. And yeah, some cell networks took years to learn that limiting phone choice just makes users switch to a different cell provider.
