If this is successful in the first iteration, I'd love to see a UK and EU based charities too. That would allow european donors to support on a gross pay basis, and may simplify grants to european nationals too. (I'm sure similar things apply in other jurisdictions too.)
Most likely we won't create our own subsidiaries, but will partner with local nonprofits (suggestions are welcome), which could make donations tax-deductible for UK/EU residents.
As for grants, we are totally fine with supporting European open source maintainers now. OSE has a global scope, limited only by the available payment infra and US regulations.
mmh. be very careful when choosing those. Esp. in former socialistic countries, and esp. in some of them (hint), where $$$ scheming has become bread-and-butter of the.. kind-of-former-but-new aparatchiks.. it's like an official mafia. Electrically speaking, they manage to find ways to ground and leech on any potential.. $100 or $100M alike.
otherwise - great initiative. The Commons (as of ivan ilich) need support and care in order to be .. there when needed.

Will take some time ofc but good to plant the seed now. :)
