"Wikipedia is centralized and transparent. Wikipedia pages have unique URLs with an attached edit history. Changes can be made for free, by anyone, and whenever a change is made, everyone immediately has access to it. New information propagates quickly. If an error is introduced, you can undo or correct the change as needed."

Changes can't be made by 'anyone'. There are now zealous content moderators that will block changes they don't like on almost every major wiki entry.

It has the illusion of being free, so the narrative can be changed by a few people. I stopped using Wikipedia as a real source of information years ago.
