I've reported thousands of bugs. Maybe 30-50% of them used to be fixed. Nowadays I'd be pushing it to say 5%.
I've gone to report GNOME or Ubuntu bugs, only to find that the problem already has a bug report from 5 years ago. The bugs are still open and unfixed, with a poor sap adding a "me too" comment every few months.
Before there was a feeling of progress: report a bug, see it fixed. Now it's report a bug and silence.
