Wikipedia suffers from massive bias and subjectivity issues, and also from accuracy problems. Yet, all the attempts to do better fizzled out so far, and most non-niche knowledge and information repositories have the same or worse issues.
I think some subjects are just not fit to be learned by reading a biased encyclopedia article, such as political subjects. These subjects are better learned by instead reading forum debates, where several biased sides duke it out. A wiki article will just have the bias from one side.
If we look back at history, many of the earliest written works were published in this way, as a philosophical debate between different fictional characters.
However it seems increasingly difficult to find good online debate with several sides of an issue. People tend to silo themselves into their own bubbles, and denounce any platform who even dares to let an opponent speak his mind. I remember just a decade ago where you'd find all opinions on the spectrum on the same message boards. Now, people prefer to shelter themselves instead.
