I can understand that the real world isn't an equal playing field, and by definition, *this* world shouldn't be either. However, I'm not much of an expert, but most governments don't stop people from posting on the internet about where they got the best deals from, or how-to guides for doing things.
Another example would be if you're a car sales man (I'm not saying that you are) being angry at sites that guides people to get the best deal on buying a car. The car sales man hates those type of sites, but the rest of the community that reads it likes it.
I also don't think I'm in the minority. I think if people post information/guides/tips/whatever, other people would read it and probably appreciate it. Only a small minority that wants to be the best (though this game doesn't really have a who's the best) would get angry because they're no longer "the best". In this game, the best players in my opinion are not the most skilled, but the one's who started first, hoarded as many items as possible and have the highest level. If you had 100 medikits, it'll take a damn long time for you to die, but it doesn't mean you're exceptional.
Going back to the realism of this world, if there really is a zombie outbreak, I would rather group up and trust other people than go out by myself, it might lead me to die quicker, but at least there's safety in numbers.
We're just speculating on what PVP would look like, but for most games, I've always like to surround myself with a group of people, and information in most games are the tools to bond people together.
