Among the many changes, the new rules would require batteries in consumer devices like smartphones to be easily removable and replaceable. That's far from the case today...
The fucking audacity to remove a quintessential port is typical Apple. Was the same with DVDs, Ethernet, now even USB. Next thing I know there'll be no more ports, you'll have to wirelessly (and inefficiently) charge your phone even if you like it or not
Not for any technical reason afaik. My LG G7 is plenty modern and has a 3.5mm jack. It also has Bluetooth, so it's not like it's an either/or choice. It's just the manufacturers dictating what choices consumers have.
