I think this ignores the fact that these devs just write some js and push it to some cloud server and it uses APIs for storage on some other server.
The person running the infra for S3 or GitHub needs to think like Linus because they need to worry about that system level compatibility. But if I write an app using say node+s3 I trust that even though I develop on x86 I can run it under node on Arm.
I think he tries to address this but fails to acknowledge it elsewhere.

I guess if you're doing stuff with low-level packages using node-gyp or C++ bindings then sure, but pure node-based workloads don't care about the architecture and, as you said, are expected to work everywhere.
