Basically, he argues that application distribution outside of the distro (a la flatpak, snap, appimage) is just a bad model. The right model is the one distros have been using for years: You get software through the distro's package manager, and that software is packaged by people working on behalf of the distro. As he says: "Software distributions are often volunteer-run and represent the interests of the users; in a sense they are a kind of union of users."
The other issue, of course, is that in practice flatpaks/snaps/appimages never seem to 100% work as well as distro packages do.
