Toxic Truth: How Wikipedia Poisons Global Knowledge
5th February 2026
Today, Wikipedia celebrates its 25th anniversary. What began as a promising vision for shared knowledge and a free internet encyclopedia has devolved into a battlefield. Today, interest groups orchestrate disinformation and chaos, erasing narratives, deleting documented historical evidence, and even distorting facts in the exact sciences.
Why does this matter in 2026? Beyond its average of 3.5–4 billion monthly visits (according to SimilarWeb) and its dominance as the top Google result for countless terms, Wikipedia is a primary training source for LLMs like ChatGPT, Gemini, and others.
In practice, this means that when fake news is injected by anonymous users who have accumulated enough permissions, it flows directly into AI engines. This cycle perpetuates lies until they effectively erase reality.
