They're offering USB ports and an Ethernet port. Apple will sell you both of those if you want them.
Though it also has an SD card reader and more battery, neither of which Apple has dongles for.

It basically reverses what Apple is trying to do by exporting everything out into separate devices which makes the machine look pretty in store shelves but a headache to use in the real world.
Also, I don't think Apple actually wants the dongle situation. This is a transitional stage where many existing devices lack USB-C. Apple presumably wants everything to either use USB-C, or be wireless.
95% of people in the "real world" don't plug anything into their laptops except the power cord.
