OMEMO is crap

I have heard of some vulnerabilities in their encryption that I haven't looked too deeply into.
Also, every client for Linux seems to require Flatpak or otherwise can't be updated conveniently on QubesOS.

Isn't E2EE in a browser insecure?

Because the server can serve malicious JS or WASM at any time.
I remember reading a blog post about it that I can't find anymore.
