Agree, but non-profits can rely on other non-profits, foundations or similar entities, rather than for-profit entities, and you're still collaborating with the world at large, just avoiding one particular hairball that has a tendency to infect everything it comes into touch with.

Sure. But this is exactly why we'd be better off with open-source software, hardware, etc, managed and maintained in a distributed fashion by nonprofits in many different countries. (I have no idea if there's legally such a thing as a "multinational nonprofit", though certainly such things exist in practice—eg, Red Cross, Doctors Without Borders.)

Any for-profit company is highly incentivized to keep their products proprietary, locked behind copyright, obfuscation, etc, or even provided only as SaaS. They are also highly incentivized to avoid the negative attention of the governments of any of the countries they operate in, because their primary goal is to remain profitable.

Nonprofits do not have that requirement, and are much more likely to be able to attract people who are willing to defy oppressive, censorious, or outright fascist governments in order to continue to provide high-quality software & hardware to everyone without limitation or discrimination.
