I did read what you wrote:
Blaming the game for something players are doing. People were doing something undesirable before the cutscenes could be skipped: Rushing people through what is a sizeable chunk of the main story. Agreed this isn't optimal, but I will never excuse people doing rude things just because it's what's convenient and the system could be better.
Yes, plenty of suggestions, lots of which involve entirely reworking old content that most players choose never to do again. But right now apparently the easiest solution was to make it not only optional for everyone who has passed that point in the story, but quite worth the time investment with little to no chance of failure.
I didn't want to start the argument about what was wrong with MSQ again, so I focused on your overall message:
It's SE's fault they did it this way, AFK'ers are just a result of their decision.
While you are not defending the people choosing to AFK you are saying that we should give consideration to the fact the encounter itself has great problems. I do not feel so. People who choose to do the cruddy thing are still choosing the cruddy thing, regardless of HOW cruddy the encounter it is they are making it worse.
