Internal DEI initiatives are very helpful for an organisation trying to create a comprehensive knowledge base without falling to any group's bias. That requires diverse perspectives.

I don't care about internal DEI if the job is managing sewerage systems, but this is a perfect example of a context where fostering diverse engagement is both rational and improves the end product.

Posting this without actually looking at what these stand for is more than useless.

People need to be paid. People want benefits. People need to be taught how to edit. Children need to be taught how to research. People need to be brought together to figure out where the site and the tech is going. People want to feel safe participating in their community. If Wikipedia had only ever been "server costs" it would be nowhere close to what it is today.
