This is one of those things where I can't tell if the writer is more angry about the practice or the social media bubble the practice came from because it's extremely annoying and, let's be honest, calling putting away groceries "decanting" ridiculous enough to make anyone spill ink ranting against it.

However, I have some personal arguments in defense.

1. Space. We have limited space, putting things in glass jars helps keep the space uncluttered so we can efficiently use the kitchen. It's much easier to store and retrieve 5lbs of coffee beans in a jar than dealing with the individual bags
2. I don't know why, but my brain works better when things have a place. It's something I just found out about myself, and now I'm deploying it everywhere. If you tell me "I bought this to pasta in" I'll become the most dedicated pasta storer you'll ever meet. If the pasta doesn't have a home, I can not guarantee that it will be stored indoors
3. Tortilla chips. I don't know what they're doing in the tortilla chip factories, but the bags they're coming in these days are made of the flimsiest material known to man. As soon you open them, the bag starts tearing right down the middle and no bag clip can save it. So now I just immediately through them in our tortilla chip freezer bag

I do. I do want to spend my wild and precious life decanting dry goods, and I even want to call it decanting! (pantry pedantry)

Worthwhile for the reasons mentioned and also because of ants, who have no respect for a chip clip.

The one time my mother tried “decanting” in the 90s she mistook the pancake mix for flour (which was in an identical white porcelain container) and ended up serving oddly sweet lobster Newburgh at a dinner party.

She kept everything in its original packaging after that.
