I don't understand the dichotomy you seem to be trying to uphold. Wikipedia provides information but not truth? What is truth?
Here's the start of our article on the Eiffel Tower:
"The Eiffel Tower ... is a metallic tower built on the Champ de Mars in Paris ... and is nowadays the most famous landmark and symbol of Paris."
This is information. And truth.
When we say "Homeopathy is a pseudoscience." we are also providing information by writing down a true statement. If I may paraphrase a couple of sentences from a certain sci-fi franchise:
One of the first things to be learned in critical (or scientific) thinking is to distinguish between statements of fact and statements of opinion. To be most effective that approach must be applied with absolute rigour. Let's deal only with the Eiffel Tower statement, since it doesn't have the level of controversy that one might associate with homeopathy. That the Eiffel Tower is a metallic tower is a statement of fact; that can be directly observed, but even that assumes that there is no controversy about the nature of metal. That it is on the Champ de Mars in Paris is a statement of fact. The naming of places is arbitrary.
That it is the most famous landmark in Paris is a statement of opinion. Fame is a question of opinion. There is no way that you can go the Eiffel Tower and perform any physical test that will establish its fame. It is not a falsifiable hypothesis.
It is information, and it may be true, but it is not a statement of fact.
