alt Hacker NewsI don't really understand the author's conclusions about cost and shipping, and how RISC-V is cheaper and more accessible to people outside the US and Europe. He first talks about how getting $1 worth of chips can cost $60-$200 in shipping for him due to his location... but then by the end claims that RISC-V gives him "an architecture that arrives in my country at ten cents a part".
I don't get how both things can be true. The cost to ship something to Trinidad and Tobago has nothing to do with whether it's ARM or RISC-V; shipping the same weight of either kind of chips should cost exactly the same amount. Yes, maybe the chip cost itself of a particular ARM-based model is $0.15 while the equivalent RISC-V chip costs $0.10, but if the issue (for him and other people who live outside US/Europe) is that shipping costs are orders of magnitude more expensive than the thing being shipped, that chip-cost difference becomes irrelevant.
I think he does make a great point about how fragmentation does give you better optionality: ARM is sort of like cable TV where you have a small number of product categories that each bundle a particular set of features, whereas with RISC-V you design something bespoke that does exactly what you need and nothing more. But again, this isn't going to affect shipping costs.

In addition to what you wrote... what does China use? One could argue that the factories there have very low cost of shipping + economies of scale - they order thousands of units, if not tens of thousands.
Then probably RISC-V being "open" license is the key to its success, even if the architecture itself is weird.
He's saying that shipping from the big western parts suppliers (Digikey, Mouser, Segger) costs a lot of money. When ordering from AliExpress or Crowd Supply he just gets the cheap postal rates which from China are free. It is very likely a good chunk of the overhead from western part suppliers has to do with export controls and risk aversion.
Aliexpress doesn't do any ID verification hassle. This is all an argument more about distribution and shipping. RISK-V is going to win because getting the parts is insanely cheap and without overhead.
The "fix" is probably Digikey, Mouser, and Segger need to just let buyers check a box where they assume all liability and parts are just thrown in the mail and forgot about - something aliexpress is great at doing.
