That’s really the crux of the matter… there really isn’t any funding, so the availability of beginner-friendly materials are based on volunteer efforts or what people can do “on the side” of their otherwise funded jobs. These things accumulate over time, though, so that situation is not hopeless. It would absolutely be great if there was room for more concerted efforts to fund people specifically to produce such material.
At least one famous counterpoint is ASML. You might find their JuliaCon talk intereresting: https://www.youtube.com/watch?v=uYhQHMtHJrU (as well as their talks in previous years).
I realize that doesn’t address your particular problems, which are definitely legitimate concerns.
