Perspective from someone who maintains Debian packages in the community repo here:

Package maintenance is time consuming and difficult. It requires a lot of volunteer work. Individual maintainers are overworked and unpaid. Packaging software often requires managing complex dependencies, writing documentation, developing packaging toolchains, and patching software.

Furthermore, stable release of a particular software version is even more of a challenge for package maintainers. Often upstream FOSS maintains only patch HEAD and release a new version. The responsibility of backporting changes to previous versions is left to package maintainers. To provide secure versions of old software, you're asking maintainers to have intimate familiarity with the OSS code bases and follow the dev process etc.

If I had community supported software exposed to the internet, I would be very concerned with the current state of things. I would want to ensure that individuals are invested with maintaining this software in a full-time capacity. It is important that "main" receives free Updates. Ubuntu Pro seems like it enhances the OSS ecosystem. As an personal user, you can get a free subscription courtesy of Canonical.

It is important to remember that as the end user, you are choosing to enable the community repo. Without Canonical, you wouldn't even know this version of the software is vulnerable.
