They've shown time and time again over the course of the game that people with the echo have resisted being tempered, more than enough visual evidence through the storyline to prove that the echo provides protection from tempering. In Stormblood we were seeing echo users including Arenvald actively block tempering. Remember the instance with Lakshmi, where Arenvald and our characters block the tempering energy to protect the people with the echo shield? Even Fordola, who has the Resonance, which is a copy of the echo, was able to do the same thing. There is absolutely 0 things to clarify, the echo and blessing both protect from it.
