I think there must be teams that work full-time on contributing to and editing Wikipedia pages to keep them in line with establishment dictated thought.
It's not a coincidence that Wikipedia suffers from philosophical bias.
In theory, such biases shouldn't exist, because it seems like access to becoming a contributor to Wikipedia is open to anyone.
But somehow certain group seem to be involving in swaying pages to suit certain viewpoints, and those viewpoints are the ones the establishment try to brainwash everyone with.
That has turned Wikipedia into a misinformation or disinformation site.
Similar to what has become of Google as a search engine.
The internet has been curated to promote prefab establishment ideas and to eliminate or marginalise views that contradict them.
