What is "high voltage programming", and why do some MCUs use it?

This article on sub-10 cent MCUs mentions that many of them use a high voltage programming interface. What is this, and why would a product use it over a "regular" 5V or 3.3V programming interface?

EEPROM technology uses a high voltage to charge the ‘floating gate’ cells in the device.
