This change is bad for new players. Fewer people are going to queue when the dungeon takes so long. Which means longer queue times for new players. And the longer the cutscenes remain unskippable, the more people are going to opt out of running MSQR. Which means longer queue times. It will get to the point where a new player will be waiting over an hour just to progress the story. This is going to run off new players. Which means a loss of revenue for SquEnix. And they're going to tell their friends "It's a good game up until you need to run this one dungeon. You can't get a group for it. I had to wait two hours when I tried to run it and I eventually just gave up." Which means less new players.

Objectively, this change is bad for the game and new players. I don't know what the best solution was for the problem, but I can objectively say this was far from a good choice. It is objectively bad for the game.
