Being true doesn't make something not defamation, it just makes it *exponentially* harder to win a suit on the grounds of alleged defamation. Basically, when the information is factual, the person being published about would have to show that either it was somehow more likely that the publisher was providing that information solely from sense of malice (eg, the information is relatively confidential and does not serve any kind of public interest, such as publishing that a person had cheated on their spouse), or else the factual information is provided in a way that a reasonable person might come to an unfactual wrong conclusion about the matter, usually because although the provided information is true, relevant facts are unstated which could significantly alter the kind of conclusion a reasonable person would come to. For example, suppose that a person has a legitimate medical reason to have a prescription for morphine, and they are required to be consuming fairly high dosages of it regularly, and then someone goes and publishes that this person appears to have a morphine addiction (which can be reasonably argued to be true, since they are only publishing that is how things *appear*) because of how often they (factually) use it, then even though the information can be considered factual, that person might reasonably be sued for defamation, but even then, since the person being published about was actually taking high dosages of morphine, the publisher of such information could probably claim genuine belief on their part as a defense and the defamation suit would likely fail. The onus would be on the person suing to show that the publisher had somehow deliberately framed the facts that they published in such a manner as to create an impression that is *not* factually true. This is not necessarily always impossible to do, but it would also probably not be a remotely easy thing for the person being published about to accomplish, no matter how much money they spent on lawyers.
