Wikipedia survives while the rest of the internet breaks

Wikipedia has plenty of propaganda. It's often at the fringes of knowledge, in niche subjects where there isn't yet an established group of proponents and detractors. It can be quite subtle too, will fool most laypeople, even those who are otherwise intellectually savvy.

It's only when a subject becomes popular that the propaganda gets recognized and rectified.

And? Share an example. This reads like conspiratorial thinking without any evidence.

I came across a similar thing when I first read the Wikipedia page on 5G was it was in development. I read it after learning an early phones 5G power consumption was through the roof, and I was trying to figure out what benefits 5G had. I was accepting everything I read at face value, until I came across the section waxing lyrical about 30GHz. I knew 30GHz was stopped by glass, or a human hand, and so was more or less useless in a mobile phone.

So I re-read the entire page, this time looking for signs it was written by marketing rather as a factual document. Of course it was exactly that. Only the engineers deep in the bowels of the organisations developing 5G knew how it would perform at that stage, and evidently they weren't contributing to Wikipedia. Until the man on the street had experience with 5G, the marketing people were going to use the Wikipedia page on it as an advertising platform.

So I'm in agreement with the OP. From what what I can see a Wikipedia page that only has a few contributors it is no better than any other page about the same subject on the internet. The breath and depth of a Wikipedia page on a subject arises because of the wisdom of the crowds contributing to it. If there is no crowd, it's possible there is no wisdom.

Fortunately Wikipedia does have one other advantage over a random Internet page - you can tell when the have been lots of contributions. There is an audit trail of changes, and you can get a feel for the contentious points by reading the Talk page. That contrasts to getting the same information from an LLM, where you have no idea if you are being bullshitted.

As you might predict from all that, the Wikipedia page on 5G is very good now.
