Perhaps they have reduced maintenance but I noticed a lot of old poles being replaced proactively the last couple of summers.
In my neighborhood they replaced guy wires and anchors this past summer. Many of the outages were caused by trees uprooted and toppled by high winds. Predicting which trees might be uprooted is not easy. Cutting everything within 50+ feet would not be welcome in most neighborhoods. I live in a city and lost power for only about 6 hours.
