You're conflating development budgets and marketing budgets. Redhat could invest 200bn into Fedora or any other project, and still people won't switch to it because even if it's "better" by some arbitrary metric, it's not what people are used to. It's definitely possible, but it looks like Linux is more likely to gain popularity via WSL than via Fedora or similar.
