Apple are known for making radical decisions.
They are, but for things that
1. are already on their way out because of declining usage
2. have retrocompatible alternatives
For example, CDs were on their way out when Apple removed the SuperDrive AND had a viable alternatives (external SuperDrives).
For USB-A, same thing: on its way out; adapters.
eSIMs do not have retrocompatible alternatives. If the mobile network doesn't support eSIM, you're out of luck. AND the situation is quite messy (e.g. some network not allowing eSIM transfers, or using plastic QR Code eSIMs which requires a new one when swapping devices).
Plus a lot of people, especially businesses won't like the inability to just pop out the SIM and put it in a new phone.
Apple could pull it off in the US because of their marketshare, but anywhere else it'll be a failure. I'll be the first person to tap out. Including for the business I own.
