That's good advice. I don't have a lot of fully enclosed fixtures, but there are many fixtures where they are almost completely enclosed (just the end open with the bulb up inside).

Heat rises, so a light fixture needs some openings at the top (unless it's a light that's on for short periods of time).
The two most common causes for (quality) LED light bulbs to stop working is heat (at 40C temperature surrounding the bulb a bulb lasts half as long as when the surrounding temperature is 20C) and the use of dimmer switches (we Dutch love our dimmer switches). Not all LEDs are dimmable and those that are dimmable need exactly the right dimmer switch. I have yet to find one that's truly universal, though many claim their dimmer switch is.
That being said. When LED bulbs started to appear they said they would last 50,000 hours. Now most manufacturers lists the life expectancy at somewhere between 15,000 and 25,000 hours. So really not much longer than a good quality CFL bulb. Though a LED contains less toxic crap than a CFL.
