Free as in embrace, extend and extinguish

Why do the current kernel developers forbid use of the DMA-BUF API to non-GPL drivers, most notably NVIDIA's? Isn't this a violation of my freedom to have better drivers? Why does EXPORT_SYMBOL_GPL exist in the first place anyway? If a module is statically linked to the kernel at run-time, the GPL shouldn't apply as it is dynamic. Why doesn't Linux have a stable module interface? Oh, right.

Why do you want a stable module interface? That brings absolutely no benefits what-so-ever.
You mean being able to use discontinued or infrequently maintained modules flawlessly isn't a serious benefit? Most importantly, a stable module interface would dramatically lowers the maintenance costs of the Linux kernel and force its developers to actually design good interfaces and document them. Such thoughtful design would also result in increased performance.

There is not nearly enough manpower for those systems to make them usable. Also, BSD and Solaris audio suck even more than Linux (quite a feat!).
