I’ve seen many threads suggesting products but they often don’t mention FOSS projects, which should always be preferred to corporate software. With FOSS you are already boycotting capitalism, on either side. Free and Open Source ignores borders and shouldn’t be categorized in nationalist terms, no matter where some of the maintainers happen to live.
FOSS is definitely not boycotting capitalism, but its still an objectively good thing. I see FOSS work as a way for relatively rich imperial core citizens to give back to the world.
Definitely do not boycott FOSS projects.
