Technically, ARM is a RISC clone (not the other way around), but locked down and loysensed out to whoever pays them to use it.
It's just that RISC started gaining traction just recently.
Though not sure if I'd really support GNU in finishing Hurd after them having stalled it 31 years ago in favor for the Linux kernel, because even though Stallman is seemingly more tech freedom aware than Torvalds is, every single GNU tool is bloat, so I'd expect Hurd to be bloat as well when that gets developed again.

But I can sympethise with the Linux kernel being so bloated in a way, because there's so much more hardware today than there were a decade ago, they all require a separate driver which are all probably very bloated too, and on top of that most of them are proprietary blobs or poor attempts on rewriting the driver too.
But I could be wrong on that, because I need a proper comparison between Linux and Linux-libre in order to actually be sure.
