It's been five years since USB-C became standard on MacBooks and we've seen Apple reverse course on the idea it could replace everything, and with the exception of a handful of ultraportables, most PC laptops and motherboards still include 2+ USB-A ports as well as other IO. In other applications, like cars, aircraft, public charging stations, USB-A is here to stay, and the advantages of USB-C are dubious at best. A more fragile port, for... what, reversibility?
Having a clear use case for a port is invaluable. When I plug in an HDMI cable, I know it's going to be used for display output. MagSafe? Power delivery. USB-A/Firewire? A client peripheral connected to a master computer bus, like a printer or MIDI keyboard. USB-C eschews that philosophy entirely. In a way, it's almost like a step backwards to the days of serial ports and DIN cables, with different standards competing for supremacy and no way of knowing if Thing A works with Thing B without trial and error.
