I bought a MagSafe puck two months ago and it was USB-C on the charging brick side; there has never been a MagSafe puck that used Lightning on the charging brick side. Apple has never made a charging brick that had a female Lightning port; Apple's bricks have always been Firewire, USB-A, or USB-C.What do you plug the other side of the MagSafe into to energize the hockey puck? Thats the part i suggest should be USB-C. That would require the USB-C charger…
Firewire 400 and 800 were not proprietary; they were open standards. Firewire was actually very popular with audio equipments, and it was significantly faster than any USB alternative. USB just brute-forced its way into popularity.Regarding Apple using lightning for longer… they may have, but apparently the industry has chosen the USB-C open source standard as opposed to the proprietary Apple Lightning… and its not the first time Apple wanted the whole industry to use their proprietary data transfer technology… Remember Firewire and FireWire 800? We don’t see that incorporated into many things anymore, and ever really did.
