I'm out of the loop, can someone tell me why Hacker News loves RISC so much?

  RISC-V, in particular. Legit question. In a word, it's hackable.

  RISC-V is open source rather libre. It's an ISA which anyone can use, and in a sense cannot be stopped. I myself believe it will be a juggernaut everyone will throw their efforts behind.

  RISC-V is an open and flexible CPU ISA, championed by the guy who invented RISC [1]. I recommend this talk [2] by him on the history of CPU architectures, complexity, and why the time is ripe for RISC-V when x86 and ARM dominate the industry (with some MIPS and PowerPC to round things off). Note that the flexibility aspect means that it's relatively easy to design a chip that uses RISC-V (of which the OP article is an extension for). Designing chips is still out of reach of most hackers, but it does offer hopes of a more accessible landscape of General-Purpose CPUs, DSPs, GPUs, MCUs, etc...
