Have you heard of @nlnet? They financially support organisations & people that contribute to an open internet for all since 1997 (& they historically contributed to the early internet in Europe in the 1980s!).
If you're working on a project that "helps fix the internet through open hardware, open software, open standards, open science and open data", you can apply for a grant on their website:
