The bad press was because it was a proprietary-connector-against-a-newer-proprietary-connector.
Had Apple changed for USB-C at the time, or USB mini, it would have made the same positive press as when the Macbook Pro got back to normal (ie not “Here’s a single port for everything, go buy an Apple dongle if you want to plug a screen”).
The USB-C spec wasn't finalised until the following year and only fully standardised in 2016. The USC-C port, which Apple contributed to considerably first appeared in 2015. Micro USB, which superseded Mini USB, was and remains to be complete and utter shite. Lightning was actually well received by the tech press of the time for being significantly better than Micro USB. The "bad press" was users on this site, among others, whining about their other 30-pin gadgets.
