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.
I always like to say the fruits of FOSS labour are the common heritage of mankind. It belongs to all of us as a public good, created and maintained by selfless workers. (Nevermind the fact that most FOSS projects are based out of Europe anyways).
