There's a better chance of hell freezing over, but it would certainly benefit users. From a economic standpoint though, it's entirely unsurprising why they do this. CUDA owns, and in the AI age it's hard to beat the parallelism Nvidia offers. If Nvidia cedes their acceleration advantage, they're leaving themselves open for attack. DirectX is a funny example of this, still being closed-source despite a reverse-engineered version existing with often better performance. It would be nice if everyone writing UNIX-like drivers gave away their source code, but then the books wouldn't balance. It's a tale that's half a century old now.
