The article for the most part ignores the actual techniques that are used to push viewpoints across that actually work. One small one I remember. Imagine you want people to believe X. Imagine Wikipedia currently reads.
A says X but B says not X.
You edit it to read
A says X but left-wing commentator B says not X.
The qualification "left-wing commentator" is, for the purposes of this discussion, entirely accurate. However, the effect is that B now looks like they're biased whilst A, with no qualifying adjectives, looks impartial.
Now consider that it's entirely possible that A is _also_ accurately described as a "left-wing commentator" and you see why this stuff is so pernicious.
Anything about Israel/Palestine is crawling with minor edits like this.
