Wikipedia has major process issues that make it unreliable especially in the long term. Editors are given a ton of power to wield, the process of giving them power is not something the laymen is involved in, once they have power it’s fairly entrenched and hard to remove, and bias absolutely occurs. For the most part the bias is tempered but it is seen more heavily in articles like Gaza, Crimea/Ukraine, Venezuela, war on terror, Autism, transgender issues, war crimes of Japan, articles related to colonalism, articles related to big tech controversies, etc.

It’s something they desperately need to address because the right wing nutjobs are gunning for them and are very well funded. They 100% are going to try to put people into the editorial process or convert people who are already there to swing bias (if this hasn’t happened already). The right wing has managed to do this with the us government, they can and will do it to Wikipedia
