There's a difference between a handful of sites that use wasm and it being the mainstream way in which we write web applications and run hosted software. It's still a very very niche platform that has not fulfilled its promise of either being a first party web tool or a universal runtime.
Like, how easy is it to write a web application in Wasm? Or how easy is it to compile your average program written for a native platform to Wasm without hand picking your dependencies to work on the platform?
You're right, but wasm's goals were never to be a mainstream way to write web applications. It was designed very specifically to allow things like Photoshop, Unity, and other high-end applications to run on the Web, things that just didn't run at all, and were really important. But despite their importance, those applications are a small fraction of total websites.
Wasm succeeded at its initial goals, and has been expanding into more use cases like compiling GC languages. Perhaps some day it will be common to write websites in wasm, but personally I doubt it - JavaScript/TypeScript are excellent.
