Expensive or crap. Anker and a couple other companies are slowly chipping away at the problem, but the laptop makers have made the problem worse (see below). One of the newest Anker hubs finally has charge passthrough, a couple usb ports, a video and an ethernet jack for $70. This is the first I've seen in this price/performance ratio. To get a hub with more connectors than that you quickly get to $120, and with twice that many you're talking $200.
Apple should have retained a few more ports for a couple of years. The SD card reader and one or two other ports on for a while, and they put the USB-C jacks so close together that you have to use tethers (dongles with 3 inch cables) to plug anything in. The 'small' USB to USB-c adapters you see will overlap the other usb port, so without a dongle you run out of ports quickly. And you know, some of us still put their laptop on a riser when working and now you have all of this shear stress because the dongles aren't long enough to touch the desktop. Dongles floating everywhere.
