It's my understanding that WASI is using Unix-like abstractions, because they also target native execution, while the AssemblyScript would prefer web-like abstractions, because they exclusively target the browser. From your second link at least, this seems like the main technical complaint:

> Languages that would naturally fit the Web platform not only are overlooked, but WASI's self-imposed abstinence of Web concepts undermines other languages' interoperability potential with JS and the Web platform specifically.

The problem is that objectively, the web platform is garbage. Half-baked, weirdly incomplete abstractions, most of can only be rationally explained as either historical accidents or the aftermath of political fights on standards committees. Why would anyone base a new abstraction around those if they don't strictly have to?
