That is nonsensical, nobody is putting a gun to your head to use all the ports. Having them available is definitely better than not. And if you prefer dongles, keep using them.
i have 4 usb-c on my macbook of that one i used for a usb-c to displayport to connect to my 4k monitor and the other is used for a dongle, i dont know what this guy is talking about, to be honest i would love to have one regular usb to not to have to carry the adapter or dongles everywhere.
