Balkanization -- full steam ahead

1) An organization being a multi/inter-national project doesn't mean that it's magically exempt from jurisdiction in every place where it's members live and do business. Cyberspace is _not_ an independent domain from the "real" world, people are made out of meat, not sci-fi beings of pure thought energy, they eat food and live in places. on earth. where every square centimeter of land is subject to some sort of rules.

2) The Chinese government are currently competitors of the US government in international influence/relations and resource extraction, but not enemies in the way the Russian government has made of many nations for the way they behave with their neighbors. Sometimes international politics is just teenage middle-school drama, with more resources, with somewhat arbitrary emotional decisions, but I don't think this is one of those cases. This is different than say a ban of Huawei telecom equipment, which is subject to the rules of the place it's members live and do business, including having lawful intercept features, that the US government isn't comfortable allowing (which just incentivized the Chinese intelligence services to compromise the US CALEA lawful intercept features of its own domestic equipment instead, lol) which is more about the competition between US intelligence and others in gathering and protecting information.

3) The hypothetical situation where the organization that any developer works for becomes a sanctioned entity by some other nation who's jurisdiction matters requires a different geopolitical alignment to make sense, either someone's host nation authorized something very bad that pissed off a number of other powerful nations, or the leadership has changed to someone who has an irrational animosity and the power to enforce it. Either way I don't think trying to anticipate such things as if you control the outcomes makes a lot of sense, where you have influence over your local government please exercise it to advise them not to do stupid self-destructive shit, but you have almost no responsibility for or control of the decisions other nations governments make, sometimes your government has influence but you as an individual have almost none.
