The platform that works closest to this is https://www.liberapay.com/
It used to allow making 1 monthly payment and spreading it between projects. But they had to change to comply with banking/payment platform rules so each money transfer is directed to one beneficiary from the get go. Meaning you setup a recurring payment per project.
There’s also the nlnet foundation https://nlnet.nl/
It’s possible to give them 1 recurring payment to support OSS projects. But they manage how the money is split between projects and their own overhead. You don’t pick the projects.














That could be handy for poor souls forced to use Microsoft office/copilot 365.
Thinking of it, it would be even nicer to have an office theme for LibreOffice/onlyoffice/… to migrate away from office without management noticing.
