I've been on both sides of this. Absolutely sucks as a user falling prey to stalebot or some poor sap pretending to be stalebot, but when I was working in enterprise tech support it was a huge relief to close a case and get it off my plate, for any reason. We had to take 2 new cases per day minimum, update each case (I often had 20+) every few days minimum. Only a small minority were a quick and easy solution (like security vulns with a fix ready we could send the customer were the easiest). We were stuck with our cases also, you couldn't give them to someone else unless you were out sick pretty much, and you'd get them back when you returned unless by some miracle the other guy fixed their problem. An inactivity close on a stalled case was comforting, I was finally free. I think they started cracking down after a bit and said you had to check in with them 3 times x days apart first instead of just immediately closing after no word for 2 weeks, and then they wanted you to call them first. Absolute nightmare.

I think as long as the issue isn't stuck with any one person then it's easier to leave open until it's actually fixed, like the 20+ year old Mozilla bug reports. Big corpo bureaucratic nonsense just ruins everything.
