This could be seen as a tacit admission by Apple that they weren’t able to move the market in the direction they had hoped. People are too married to their HDMI cables and SD cards and simply resorted to using dongles to get around them and usb c accessories haven’t quite taken off the way Apple had hoped.
Which is weird when you think about it. Most laptops have at least 1 usb c port these days, but not everyone has a HDMI port due to their thinness.
It took forever to move beyond VGA, and it will probably be another eternity before people are ready to switch from HDMI to usb c. Feels a bit like a belated middle finger from Apple. You all complained that you wanted HDMI, I will give you HDMI, but you will still have to use your usb c port for all your fancy, hi-res monitors.
