Because this is not actually useful in any way whatsoever. The point of citrix is accessing legacy desktop applications running on some server via a light desktop client. The whole point of that is not having to replace those legacy applications and not having to install them locally. The business is allowing companies that have ancient stuff being able to continue to use that. It's worth a lot of billions because lots of companies just have decades worth of software that their businesses depend on. You are right that citrix should be able to dumb down what they have to basically a glorified web application that accesses their servers. Which apparently is a thing for obvious reasons (as in they thought of that too, many years ago).
