I'm afraid you're right about that; there is definitely a lot of obsession behind this :-) and most of the time it really is not that big of a deal if one of those updates is running a bit late, but every now and then it is, and that been said, I completely understand why someone, supporter or not, would be upset about it.
In an example, this past weekend as I hear, some people weren't able to watch their semis. Now, that is a shame. I would imagine very few of them, if any, optioned to watch replay of the game afterwards.
And one more thing, everything affects transfer market :-) I really wouldn't say one update is more important than other.
