While USB-C and DisplayPort have taken over most external displays these days, plenty of all-in-one USB docks still use DisplayLink. Not every device supports DP ALT mode, and some devices (like several of Apple's M chips) don't support more than one external display over DisplayPort, making it a necessity to fall back to alternatives like DisplayLink.
