Will RISC-V become forbidden technology in near future?

I think managers from big US companies will speak with politicians and explain them how the things works.

Open Source/Hardware things works worldwide and it does not make sense to ban them. Maybe lobby from comercial competitors but otherwise it does not make sense.

Many big vendors plays with RISC-V even their flagship chips are not powered by RISC-V. For example, Intel use them in FPGAs. The only company who stated that will not in near future switch from arm is ST.

It would be pretty ironic if the US prevented US businesses from reaping the benefits of this technology that was actually developed in the US. It seems like a good formula to cause the US to fall behind in the technology race and mainly hurt US businesses.

I suspect it wouldn't matter - the US isn't the whole world. In fact, it may well make them less competitive to have a position against an open technology.

Given so much semiconductor manufacturing and electronics manufacturing happens in China, what China chooses to adopt will likely have a bigger impact on the world. Just look at all the ESP8266/ESP32 chips out there rocking a Tensilica core doing lots of useful things in the world ...

Even esp32 comes with RISC core now.

If their problem is losing monopoly over global chip supply, surely they too can start creating chips with RISC architecture. I am pretty sure the companies will save millions when switching over from ARM to RISC by avoiding royalty and related fee. 

Sounds like ARM might be using some of their IPO money for lobbying the government to slow down their competition. 

Not according to the form F-1 (aka the "red herring"): "All of the ADSs to be sold in this offering are currently held by the selling shareholder identified in this prospectus. We are not selling any of the ADSs in this offering and will not receive any proceeds from the sale of the ADSs by the selling shareholder in this offering." The selling shareholder is later identified as the Softbank Group.

Apple and google don't need RISC-V, if they want to develop their own ISA they very well could. 

I think the CHIP industry will change again in a year. All manufacturers and engineers involved with architectural development are not ignorant to the future technologies being developed by other countries. There is a small circle of individuals that know and control the direction. My guess is they are American. That will not change no matter what some propaganda a politician is pushing... 

These RISC issues come and go.

I have seen a number of RISC implementations over the last forty years or so, they have all been championed by someone, but usually disappear over time.

You need a whole lot more than a hardware design to make these things happen.

It took NVIDIA a lot of years to create an environment where others could take their hardware and turn it into something useful.
