I can’t speak to people’s motivations, but I have been a very active member on this forum for a long time, and I was on the Rust team for about a decade, beginning before 1.0.

So the article is more like “Here’s why I started using Rust. If you thought I made a good choice then, well, I’m making a similar choice in case you want to join me.” Seems people find that compelling.

Just like Rust’s success was not inevitable, neither is jj’s. But I think it might work out.

You could also consider this a disclosure of sorts, I post a lot on this forum about jj (and Rust), and so knowing that I now have a financial incentive is important context to some people.
