They don't like to talk about it since the reality will undermine popular myths. Some of the 'dirtiest' electricity an appliance might see comes from a UPS in battery backup mode. For example, this 120 volt UPS outputs 200 volt square waves with a spike of up to 270 volts. Ideal power for any electronic appliance. But potentially harmful to small electric motors and power strip protectors.

They will say why with numerours irrelevant comments. But the bottom line: that above sine wave output UPS is that 'dirty'; that potentially harmful to the protector.
