As noted here, https://www.macrumors.com/2018/05/08/ios-11-4-usb-restricted-mode/ as well as other sites, intends to disable the lighning port if the device is not unlocked or connected to a computer using a passcode. I personally know of three devices that haven't met the conditions and would be locked. Believe it or not, there are folks that do not use passcodes, there are folks that haven't connected their idevice to a computer for months. While I understand wanting to increase security, there should be an option to disable this "security" feature. One option could be to give an option to disable this feature upon installation of 11.4. IMHO, and only for me, is pushing me out of the ecosystem step by step. GIVE ME THE OPTION!!!!!
