Not all of us. I fervently wish that implementing the various platform-specific accessibility APIs, and the corresponding tricks for canvas-based GUIs in web applications, was easier, so more GUIs would be accessible. I wish I wasn't one of maybe a few hundred people in the world who had substantial experience with the UI Automation API on Windows, for instance. I'm working on an open-source project to try to package up that specialized knowledge in a reusable implementation. But it takes work to make inherently complicated things easier.
