What are some of the open source projects you support financially?
This year I donated to (in no particular order):
Regolith (desktop environment), Amfora gemini client, Thunderbird email client, Lurk (server, community), Merveilles (server, community), Neovim (text editor), Imagemagick (image editing swiss army knife toolkit), ffmpeg (video editing toolkit swiss army knife), Krita (image editing software), Wikimedia, Kde (for kdenlive and Ghostwriter), Love2d (Lua videogame framework)
and possibly some more i'm forgetting.
Rather than direct my money to subscription services I try to pay donations to the open source software I rely on daily.
