It's not a protection racket at all: you can go apply the patches yourself from upstream. See https://canonical.com/blog/open-source-security-with-ubuntu-pro https://canonical.com/blog/open-source-security-with-ubuntu-.... > Alongside Ubuntu itself, each of these applications is fully security patched for high and critical CVEs for 10 years.
