One can feel rage if something is intentional and annoying, unintentional but annoying, intentional and not annoying, unintentional and not annoying.

The first is justified. The second is understandable but a case of confusing it with the first. The last two also happen, and are not justified nor understandable.

Unfortunately there is currently an excess of the first case. I think people are arguing this is a problem. It probably causes the other 3 to happen more too.
