I don’t think that’s correct either, if the community is in arms about something they will change things but not always for the better. For example, previously the debuff did not continue if you downed one boss. The result is that tanks would leave after the 1st trinket boss so they took the feedback and changed it to all in-progress runs.
Or that they changed that players who leave Blitz etc receive a stacking time and score penalty. Despite if they may just have had a disconnect issue (so not intentional leaving) which I still see threads regularly pop up about it.
They do change things, but it can get worse if they just blindly listen to the people demanding to take protections away.
Trust me, removing this and not putting anything at all in place would grievously make the DPS experience in Dungeons extremely worse. You wouldn’t be able to start or continue a dungeon because tanks and healers would just continously leave until they get where they want to be.
