All fair points. Sorry, I spend a lot of time on regional forums, and I had a brain malfunction and forgot that when I write on HN, I am writing on a worldwide forum. Sorry for the unnecessary nitpicking.
Re non profit, I do donate to a few nonprofits I like, like those working on fediverse and my favorite langs. But I don't know of anything that does this for extensions. I'd have definitely voted with money if something was there. So, yeah, no, I am not doing anything to start a nonprofit for extensions. You have a good point.
