The issue is that it was the DE originally, some people (myself included) just didn’t fully get the memo when it changed like 15 or so years ago. I haven’t used the KDE DE since before that change, so I get how it could be missed. Rebranding is hard, even years later. I am sure many people think KFC still stands for Kentucky Fried Chicken too.

Reminds me of the informal study where people kept choosing pizza that came in more/smaller slices because they thought it was more pizza.
