The answer is to push the "application vendors" back into the browser. None of them are really writing anything that needs to be running natively, it's almost all just a front end to some service on the internet.

Real computer applications are almost universally developed by researchers and the open source community and look exactly like this. No "application" just tools you install into your system that are watched by the community for breakage/malware or worst case offered as a git repo/tar for free.
