Since most of what I would have said has already be mentioned I will just go with almost anything under the umbrella of the KDE organization.
As in the Plasma desktop environment and the whole application suite. Includes programs like Krita, Kdenlive and KDE Connect, plus the whole range of "standard" desktop applications like terminal, file manager, document viewers, etc. pp.
And the DE itself is just adorably hackable. Want to replace the Kwin window manager with i3? Sure it's possible, here you go: https://userbase.kde.org/Tutorials/Using_Other_Window_Managers_with_Plasma
Alright, so you don't acknowledge the problem, still fits the definition.
Fair enough on most of those areas you mentioned by the way, wars, economical depression, and the pandemic have been exaggerated, with the serious caveat on the latter that that was unclear at the time so you had to err on the side of caution. But it's kind of the opposite with climate change IMHO. Scientists have kept to rather conservative projections so as to not cause panic and apathy in the general public, but over the last years new measurements have outpaced those predictions at practically every step of the way.
