You don't edit Wikipedia with the intent of putting new information in there. The culture of Wikipedia will notice you as a foreign presence and push you out. You edit Wikipedia with the intent of improving Wikipedia. When you do that, some of your edits will add new information to Wikipedia as a means of improving Wikipedia. But that addition will have been a tactic for satisfying your terminal goal of improving the encyclopedia, not a direct attempt at satisfying your terminal goal of having this information be in the encyclopedia. The community can tell the difference.

By analogy: a small farming village has a commons. Someone who grazes their cows on the commons, then sells the milk and meat to the townsfolk, is just participating in the economy, and the townsfolk are fine with that. Someone who herds their cows in from the next town over, grazes the cows on the commons, and then herds the cows back home—and never otherwise interacts with the community? Not okay. That's sociopathic behavior. They're not a member of the community; they're just taking advantage of it for their personal benefit.

Wikipedia's editors are smart enough to recognize what someone looks like when they're just trying to take advantage of Wikipedia for their own (PR) benefit. The edits might be the same, either way (just as both farmers above graze their cows in the commons in the same way, either way); it's the context that determines whether the edits are acceptable.
