I take issue with clear PR-speak trying to make the issue lesser than it actually is. When you're having an outage- call it an outage. Having a feature completely unusable and labeling it as "degraded performance" is clearly twisting your words to lessen the outwardly perception of the scale of the problem.
Because they want to use the same language every time, and say something quickly, and litigating whether something is an outage or degradation or latency or intermittent or whatever is a distraction.
People are going to jump on them no matter what. Having a engineers talking to PR wouldn’t help anyone.
