It’s the opposite. The older the bug, the less likely it will be fixed. Those old bugs are one of the most reliable sources of information how the software behaves.

There is a huge difference between forever and 7 days of inactivity.

Especially when it’s the developer that is inactive. Like, we’ve ignored you for 7 days and now we have committed to ignoring you forever. If I find this I won’t even bother filing a report. I get that we’re not owed attention, but they’re not owed bug reports. As a dev I have won’t fixed issues due to lack of dev time. I think the problem is when it’s paid software, or an open source project connected to paid software. There seems to be a push of testing onto the users which is disastrous when combined with a policy of ignoring them. Microsoft went through a period of aiming for two testers for each dev. Post my tenure it seems that devs are supposed to the test themselves.
