I know this is an unpopular opinion, but I think Wales is correct.

I understand this seems irrational, because of course Israel committed genocide in Gaza. And Wikipedia's job is to describe reality, right?

Wrong. Wikipedia's job is to describe historical and scientific consensus. It is fundamental to their mission that they do all they can to avoid arbitrating disputes. I know that's painful, but it's a matter of roles: academics and media organizations arbitrate, and Wikipedia's role is to catalog and communicate the consensus these organizations reach.

It's terrible that a minority of biased actors have managed to prevent media and academic institutions from reaching consensus when the subject is so straightforward and obvious. But until that is addressed, unfortunately Wikipedia is hampered from describing the consensus reality by the needs of their core mission. They are designed to be downstream of these organizations, and they have to be to remain effective to their core mission. It's like how the UN lets war criminals like Netanyahu visit and speak. As much as we'd all like them to kick him the hell out, doing so undermines the core purpose of the institution. It's uncomfortable, but it's the job description.

I think one solution is that their should be more than one crowd-sourced encyclopedia for the world. Wikipedia will always suffer from a Western, English-speaking bias.
