Terms of Use for code snippets/examples within Unity documentation

Is there are clear statement on how we can use code snippets from the Unity documentation?

When trying to figure out how to use various parts of the engine I frequently see code snippets (sometimes downloadable). Examples:
- UnityWebRequest
- Vertex and fragment shader examples

Common sense tells me that these would be in the public domain with the intention that I can copy them as a starting point when creating my own Unity apps (otherwise what is the point in publishing them), however, without any other statement to the contrary, Section 1 of the Unity Website & Communities Additional Terms appears to suggest that we can't use any content from the website commercially.

It does not appear to distinguish between copying the manual, creating derivative documentation, articles, or tutorials based on the Unity documentation, and using the code in our own Unity projects.

Yay! Who would have though instead of searching I should just look at the front page!
