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.
Stabilizing might not be quite the right word I’m looking for. But for example, trying to connect a new wifi card etc. Or when one program updates but this causes instability and you have to undo the update. Even from the handful of linux wizards I know, their battle stories with updates or new configurations are enough to terrify someone.
