Pretty much textbook F.U.D.
"Get the Facts" all over again. Did not work the last time, why would it work this time?
Also, who makes an IP purchasing decision based on one-page smear site?
Executives with more money than brains, a very numerous and prominent species.
EDIT Now for something completely different.
1. CostWith RISC-V, you don't run the risk of getting sued out of your life savings as a result in a technicality regarding IP licensing. There are also no restrictions, and no uncertainties should the company either go out of business or be acquired by a company with questionable morals, who want to change your IP licensing agreements at a whim.
2. A large, supportive ecosystemRISC-V is getting there, and there are now COTS development solutions in place. ARM, on the other hand, is just the ISA, and it is critical not to ignore all the surrounding support components of a system.
It will happen sooner now thanks to ARM's FUD-propaganda Streisand-effect website.
3. Fragmentation riskSince RISC-V allows for private extensions, it would benefit those who don't intend to allow some random rinky-dink apps to run on their system as they can optimise it for their own individual use cases. The base RISC-V implementations and COTS solutions will still be available.
As for ARM's supporting infrastructure: so many combinations, so many choices, so much fragmentation.
4. SecurityFor ARM it's, like, totally no big deal.5. Design assuranceHaving one major company "verify" your CPU, or having a large community with plenty of eyes verify and find faults in the design. You decide.
