A RISC transition and a moon landing are markedly different things, though. They've already migrated MacOS to a RISC architecture, whereas nothing Apple makes is really intended to go into space. Unlike building a rocket ship, we already know Apple can do this.
None of us really know the specifics of Apple's deal, though. It's a perpetual license and they are in-bed with the firm that majority-owns ARM. It seems like a good deal, but obviously it's not good enough; Apple doesn't use any ARM-provided core designs and even adds their own ISA extensions when-needed. They themselves are using ARM like it is RISC-V, and they're a big enough stakeholder that they can get away with it.

They've been exploring RISC-V internally for a couple years now, too.
I think it is either extremely foolish or ignorant to think that RISC-V won't undermine most ARM-licensed devices. The vast majority of places where ARM is used (even in Apple devices) is small and cheap microcontrollers that mostly cost whatever their license demands. If Apple could switch their internal ICs to RISC-V, they would already be saving a lot of money without transitioning to RISC-V fully.
