I hear what you’re saying. Just remember that Cygnus Solutions and Red Hat, both prominent commercial supporter of FOSS, were based in and headquartered in the US when they were independent companies. (Now they’re both part of IBM.)

Even the Linux Foundation and the Free Software Foundation have to obey US sanctions - LF is based in San Francisco and the FSF is based in Boston.

Going FOSS is good, but the US abusing their sanctions powers is a different kettle of fish.
