I've used LEDs for much fewer years, both cheap and brand names, and have had multiple failures (from both camps). I once complained to one of the brand companies and they said the same thing about overheating in poorly ventilated fixtures. One of this fixture was not closed, but somewhat narrow (open glass cone). If that actually was the problem for that bulb - ie. such an fixture is prone to overheating it's no wonder people are complaining about LED longevity.
