If Wikipedia was called "liberalopedia", not many people would use it either.
And to their credit it didn't start out with any bias. I'll be downvoted for this I know, but it has a bias which developed over time.
For example it blacklists Fox News but allows CNN or MSNBC as valid citable sources.
To verify, and not just take my statement as truth, search for yourself "perennial source list Wikipedia".
There a whole host of other problems, including anonymity and partiality of the high level bureaucrats or admins. It started out as a good system but morphed into one with a lot of bias, because if the bias in high ranking volunteers, which is very hard to get rid of.
I do not know how Elon will plan to avoid similar bias, it is indeed a difficult human engineering problem - not necessity software engineering problem.
