That rate seems high. But, I have done post-mortems on a bad developer’s run at a company, and found they did very nearly nothing. No commits, no issues opened or closed, some comments, but that was almost their entire digital footprint.
Most developers I’ve worked with are obviously not doing nothing, though some of us (including myself) get stuck doing a lot of work on a project that never makes it into production due to shifting priorities.
I thought they had successfully converted around the time they got the infusion of funds from MS. I thought they were started as a not-for-profit, but were already shady-as-shit when they stopped publishing stuff under open licenses.
