Google’s temporary retreat on RISC-V is a good example of the kind of basic stumbling block that a new architecture faces on the road towards mainstream - the lack of a mature and unified ecosystem.
I think RISC-V is positioned well to be the preferred architecture for an open ecosystem. But that’s not necessarily going to help it compete. If RISC-V is ever able to compete with Arm it will be because some company developed a chip based on a proprietary implementation of RISC-V, that is able to outperform Arm based offerings in some key way. Proprietary is just more profitable than open, so that’s where the money is going to go, and you need money to compete.
That being said, I’m glad an open standard ISA like RISC-V exists.
