Why plastic items in a dishwasher take longer to dry than metal,glass or ceramic

For my dryer, I have a valve that redirects the hot, humid exhaust back into the house during winter.
I love opening the dishwasher and that "whoosh" of steam coming off the racks in the winter.
Another thing that helps is getting a dishwasher with a stainless steel interior. The interior then retains a higher temperature which aids the drying process (more complete dry, and faster dry).
Last, as mentioned in the article, is to ditch the plastic where possible. For storage containers, switch to glass (preferably stackable ones) so the nuisance no longer remains. As someone else mentioned, for any plastic that remains, get thicker pieces that are designed without ridges, divots or depressions that can trap water inside them.

I got a Bosch Benchmark series dishwasher and had it installed in my apartment when I moved, since I knew the one already installed was going to be a huge disappointment. Additionally it uses a filter instead of a disposal, so it runs nearly silent, which is good when you work out of your living room. No issue save for the plastics, which I replaced with glassware. Never a drop on anything anymore, even without using the hidden heating element the Bosch has (a step-up feature in the Benchmark Series). Worth every cent for the 15 years I'll likely use it before replacing it.
In the end I figured out I needed to move my dishwasher a half inch forward to make steam ventilation easier. I also try to remember to prop open the door when the cycle's over to vent even more steam to get top shelf plastic items dryer than my previous dishwasher with a heating element.
Before turning on your dishwasher, run your kitchen sink's hot water until its hot.
Obviously lots of pros and cons, but for me, it's a great tip.
Cons: Takes time. May be completely unnecessary
Pros: Hot water is "free" for me, electricity is not. Cleaner dishes. Shorter wash cycles.
I've seen some people/articles recommend hooking the dishwasher up with cold water, because the dishwasher's own heater is more efficient than your house/apartment hot-water heater. I don't know if this is true.
As dishwashers reduced their water consumption, (old ones might be 12 gallons, new ones are about 4 gallons), the amount of fill water which is "cold, before the water gets hot" increases. A dishwasher probably adds water at least twice, so that is two cold flushes in that 4 gallons.
- plastic is less dense than ceramic or steel, and thus when brought to a certain temperature it holds less heath. This is true even if plastic's specific heath (kJ/Kg K) is higher.
- plastic is hydrophobic, so water does not spread over the surface as a thin film, but collects in larger drops. These drops have a lower surface/volume ratio, and so take longer to evaporate
Interesting, but not really a problem that needs solving in daily life.
Aside from that there was also a domain someone set up called like fullnyt.com or something that would redirect to the full article by sending you via Facebook outgoing link wasn’t there? Anyone remember what it was called?
Did you check that the article really was cut short?
If the article is good, the discussion on HN can be worth reading. In fact, it can be more valuable than the story.

90% of the time I'd rather see a link to a paid source than one to the ad-revenue-hunting blogging-with-a-fancy-name Business Insider, Forbes, etc sites of the world.
If you're routinely triggering their metered paywall, maybe it's worth paying it. Not for everyone, obviously. But they do give basically all that money to writers, and they do quite often devote time and money to investigate serious issues, far more important than dishwasher physics.
