It's what SMS and flight data monitoring is all about - very likely they saw these events in their data and they did something about it. It's a superb response. Having done this work for a long time now, I know that no carrier can reasonably believe that some of this doesn't apply to them. There are no such things as "skygods", (but there may be some pilots that believe in their own propaganda...).
When the cost is so enormous, UAL's actions come under the heading of "Lesson's for free" for all flight crews and not just UAL's.
