I think this is a pretty clear example of what I mean when I say that my work was never valued.
I did do work that was non-code - I labeled tons of issues, closed duplicates and those which had already been fixed.
I did try to write code contributions (here and here). One of which was rejected based on purely aesthetic preferences and whose follow-up PR was made dormant forever afterwards.
I tried to help and contribute in the ways I could - apparently this work is just "negativity and complaints".
