Imagine it's post-2001 and George Bush is saying we need to take away Iraq's Weapons of Mass Destruction (WMDs). You hear there is a controversy around this topic, so you look it up on Wikipedia. The Wikipedia article may not even mention the controversy because it came from "fringe sources" or unreliable media, instead its rules mean they only share the message from approved media sources, and that means the article says Iraq definitely has WMDs and something must be done.

This is how it works now, and always had.

When I was in college in the second half of the 2000s, we were banned from using Wikipedia as a source due to the way it is built. Many complained but given how many controversies Wikipedia has found itself involved in which includes paid editors, state actors, only being able to use biased journalistic coverage to construct articles, refusing to use other media sources such as established bloggers...

Trusting Wikipedia at any point was the mistake. It's not even the Wikimedia foundation that is the issue, it's the structure of the site. If no approved journalists will speak the truth, your article will be nothing but lies and Wikipedia editors will dutifully write those lies down and lock down the article if you attempt to correct them using sources they personally dislike.
