Couldn't have said it better. I see it rub off on some FOs doing weird non-standard stuff that they learned from DECs.

At my airline, they act like us natives don't know how to properly operate the airplane because it isn't the way they've done it at their last failed airline.

And by the sound of it, the OP came busting in with a bad attitude that left a bad taste in everyone's mouth.... and then asked why people don't like DECs. Fitting.
