The place I worked when the USB-C MacBooks came out had a hell of a time with video output. This monitor only works with a DisplayPort dongle, this one won't work with a new MacBook at all, this one works but only if you use one specific cable, this one works but glitches in ways it never did with HDMI, et c. There came to be a whole level of cult knowledge about which laptop + cable + monitor combos would work and which wouldn't.
It was a very dumb situation. If they really wanted to go to USB-C they should have had a transition period where they just replaced the thunderbolt and maybe the charging ports, until shit settled down—which it never really did, because the USB-C cable situation is insane, so here we are, with some ports added back.
It's 2021, almost 2022, and I still wish one of the ports they'd put back was USB-A. I'll probably feel the same way in 2025. Maybe by 2030, when almost none of these MBPs are still in use, I won't still need a USB-A port way more than I need a USB-C port.
