The word “closed” doesn’t mean problem solved. It actually can legitimately mean the problem is ignored: we closed the case because nobody cared anymore.
That shouldn’t happen because people will continue to report the bug and open duplicate issues. Instead, it should be tagged with something like “won’t fix”.
Won’t fix can be such a trap as well because it doesn’t make the problem go away but signals to the users “we don’t care so go away”. The issue that pushed me off of android was tagged as wontfix, and doesn’t seem to be solved despite a decade of users complaining android is literally costing them money: https://issuetracker.google.com/issues/36907469?pli=1
WONTFIX means the developer won't fix the bug. If you still care about it, fix it yourself or pay someone to do it for you; you're not entitled to unpaid support from 3rd parties, even if you ask nicely.
Please look at the context of my comment. ummonk suggested that developers should tag closed bugs with wontfix, even if they were only closed because no one cared (rather than because they don't want to fix it).
