I don't know whether it is true or not, but the author explicitly states that it is the official applications AND runtimes that aren't properly maintained.
> I have the same problem when I run applications that have an official RPM repo, and a volunteer packages the deb and pushes it to the official Ubuntu/debian repos
No you don't, because either (a) the package was not uploaded to the official (main) debian repository or (b) the debian security team is in charge of fixing it if the maintainer is no longer available.
