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.
By donating to contributors to free and open information and software you support the movement against tyranny inside the us and also everywhere.
compared to that foss devs buying groceries is negligible to the us economy.
