If you look at their personal profile they've made a lot of content with activity and collaboration outside of the main beancount repo, related to beancount. They definitely meet the criteria for 'FOSS dev' in that it's FOSS, too.
Thanks. I was not denying the author FOSS creds generally, just expecting actual involvement. It seems this is someone who cares about the project (and I do like the sound of the project).
I'm just, you know, pretty sensitive to HN submissions trying to sell me something.
