Why wouldn't they have such a fund? Sponsoring is a viable FLOSS business model, and it heavily overlaps with support (which is discussed in your quote from the blogpost).
The notion that "people" aren't "able to make money" with FLOSS is just a fallacy, and Blender itself is one of the clearest examples of how wrong it is - it was failing as a commercial prospect, and then got "rescued" or "ransomed out" as FLOSS via crowdfunding - one of the earliest crowdfunding initiatives I'm aware of, for that matter; well before there was anything like Kickstarter, Indiegogo etc.
