thats just a short term fixes too though. the ads will get more intrusive and annoying. and at some point pro ads will just turning themselves back on. because this is a company and it wants to sell things.
Yes but Fedora is semi-rolling, something in the middle. This is about Ubuntu LTS, a traditional LTS version that cuts off packages on some random version.
This should really only be done if
The programs have a supported LTS/ESR version (Linux Kernel, Firefox, Thunderbird...) (btw GNOME, Chromium etc. dont have one)
The packagers have a lot of time, the users pay money and the packagers actually make those versions as bug free and secure as possible, while keeping the feature freeze
Ubuntu is trying to do 2. but have this separation in there to get money.
