@isotopp Ok so as someone with multiple open-source projects, I have some thoughts on this.
While people shouldn't be entitled to their issue tickets, having them at all is very valuable. So few people actually report bugs for my projects. I end up being the one to discover more than 90% of them. But when someone does report a bug, I often had no clue it existed and am able to fix it.
Just because I get a issue ticket doesn't mean it's a walk in the park to fix. But, overall they do help.
