@federico3 likewise with commit frequency/recency. Programs are not produce—we shouldn't assign high value to "freshness".
"ugh, repo is inactive" reactions presume that correctness is not and cannot be a thing and that a project can never (shouldn't?) even approach a state of being "finished".
People seem to use activity as an inexpensive but flawed way to approximate developer responsiveness. If that's what you care about, though, then focus on that instead of inaccurate proxy measures.
