Ask HN: Does anyone have OpenBSD projects looking for unpaid/paid help?

Not a *BSD user myself, but have you considered FreeBSD or NetBSD? I would wager they have more friendly communities.

Apart from the official homepages, this might be a useful starting point: https://www.unitedbsd.com/

Best of luck!

I suggest reaching out to the OpenBSD Foundation themselves…
