How quick you forget, there were a lot of people complaining about the iMac dropping ports and using USB. If you want to see what it is look, look around at the people complaining these days about going all in on USB-C.
Yep this is exactly the same. People complained about the new lightning connector in 2012 as well. The one difference is USB-C is more complex and some peripheral manufacturers haven't been building stuff to spec.
