This is true. It was really the whole browser HTML/CSS/DOM/JavaScript platform which was considered locked and frozen by IE. Flash supported JavaScript but through its own independent engine, which meant it could evolve independently of IE. Something similar was envisioned for SVG, which is why it needed its own networking API independent of what the browser provided. Of course things turned out differently, and SVG became integrated in the HTML rendering engine and browser environment.
