Really? The sentence at the top of the Donate page seems pretty clear to me:
> Your donation helps Network Time Foundation maintain the NTP website and provide resources and support to NTP developers.
Is it unclear to you?

But..it's $1k. This is basically pocket change on an institutional level. I've been part of some very scrappy and poorly funded community organizations and even they took in more than $1k every year. Even if you don't believe NTP maintainers should be paid anything for their work (an opinion I don't hold), it's trivial to spend this amount on modest everyday expenses like renting a venue a couple of times, buying insurance, and paying for hosting and technical resources.
EDIT: Here is their 2024 tax return

It looks like they took in more than $200k and spent $100k on "contract services" (I can't tell what that means) and somewhat modest amounts on other things. Unfortunately I need to exit the rabbit hole now.
