First of all I think it is great that you wanted to express your opinion to others.
That being said I take issue with this,
"I'm not interested to know that someone, somewhere, had one different game : it's just hiding the very great majority." The way I read it says something like this,
"I'm right and have weighed every aspect of the game and it is not good. Don't bother trying to debate this, you'll be wrong." Thats just the way I read it. There is much I could say about this but I try not to debate with people who don't leave room for others, either their opinions or their preferences. What's the point?
The reason that companies provide forums like that are not just to establish a community. Its also to control publicity. They can provide a central place for people to come to investigate before they buy. Sure you can go other places, but to most the "Official Forums" are the best place to get a feel for the game's strong and weak points. If I were a developer I'd do the same thing. I'm not going to put my faith in people to post responsibly elsewhere when I could moderate it myself.
I would agree that your post is one-sided and not very representative of the game. In short I'd do the same thing they did

PS
Here I've responded to you in another thread because you specifically wanted this thread for discussion about the morality of deleting posts. I'll respect that wish. But I will not let you get away with making an argument without due response. There are other people who read the forums and, despite your saying so, I don't find your opinions representative.
