Why is every gaming blog trying to ruin Batman: Arkham City for me?

Well I am going to come the conclusion that their logic is that it is in the first act, therefore not important.

Also, that's like saying this--

Pretend FFVII is set to release next month and a game blogger previews the game.  They let him play up to the point that Aeries is killed and he includes that in the headline.  It's in the first act so it doesn't matter, right?

I know it is a spoiler and a pretty bad one, but I think they would justify with that. I can't really think of anything besides that.
