With the exception of industrial and enterprise software, which remains a significant chunk. The problem with the Linux desktop is that the people developing it are completely out of touch with how the average user thinks, and they assume that introducing another opaque monolith daemon to handle an entire subsystem is the only thing stopping all those Windows users from flocking to Fedora in an instant. The result is that they alienate the people who actually care. Ironically enough, the examples you list (Google and Canonical) are ones that operate outside the general sphere of influence of the desktop developer scene. Canonical in particular is reviled as all hell by the Red Hat subculture.
