I mean literally like if the person's password was "potato##!" the customer service person would read back "potato##!". They weren't reading the encrypted contents of a pw field.
If the data can be read by so many people in the company that even the customer service people have access, it's functionally not encrypted.

Is not about functional encryption but storing directly as plain text.
I agree that it any system that allows this IS almost certainly just storing as plain text, and that it’s bad regardless.
