I don't see a solution other than every application being launched in a separate container, exposing only what the user explicitly gives access to, similar to how mobiles applications require permissions. We have the technology, eg. cgroups & unshare on Linux; what's missing is something that plumbs all these brittle pieces into a secure application launcher made for desktop (rather than server/cloud) usage.
