Thanks everyone for your comments and boosts on my last toot around collecting FOSS support programs for maintainers and contributors. This is very helpful! I went trough the comments and this is what I have so far:
Sovereign Tech Fellowship, Sequoia Open Source Fellowship, NGI Zero Commons Fund, Clojurists Together, PSF Developers in Residence, Django Fellowship Program, eBPF Fellowship.
Update: Research Software Maintenance Fund, Nominet DNS Fund.
