Can’t donate in good conscience though because they do somewhat have a general tone and worldview that seems to be pervasive and heavily moderated. Wish there was a forkable version of Wikipedia so all views and angles can be allowed to co-exist, no need for a digital encyclopedia to be so skeuomorphic.

It is forkable, you can download the database dumps and import them into your own instance.

I mean forkability as a first class feature built into the UI so you can easily browse the alternative or competing beliefs.

You're basically describing Google Knol. What you end up with is a bunch of people publishing often self-promotional, biased, or just plain bad articles.

Sounds like the UX and the concept needs more refinement. Also I wouldn’t let Google anywhere near such a product.
