I'm not talking about chip makers, but about CPU IP providers. Like ARM.
If you say there are not many publicly available products including publicly accessible RISC V cores from those companies I listed compared to ARM, yes this is true. Because they're (for now) mostly used for embedded application, deeply inside complex SoC. Only used by the chip makers developers.
A relatively small company like Andes has their IP in over 10 billions SoC today. A lot of it for things like touch screen controllers, but also more complex things now. But I'm not sure you can find a mass product with an accessible RISC V Andes core.
Still, public access has already happened with Renesas, and it will likely get more common. People tend to focus on the high end, but the most common in high tech is to attack from below. Take a foothold in the low end because you're cheaper (smaller companies with lower costs can deal with lower prices), build a customer base, then grow from this. Until one day you can attack the high end (we're not there yet IMHO). I have access to these companies roadmap and this is what I see them doing, and it shouldn't be surprising.
But this means that at this stage, the majority of RISC V use is invisible to the public. To me this is perfectly normal. Building an ecosystem and maturing a technology like this takes a long time.
IMHO we're already at a stage where ARM has real competition in the low and mid end, particularly where there's little dependency to the ISA (embedded, or simple uC programmed in C anyway with no 3rd party binaries included, like Renesas). I think ARM is still safe at the high end though, and it will take some time for RISC V to get there. Chip making is hard, particularly at the high end.
