It's a certain type of pun. Not all puns are dad jokes. Dad jokes are viewed negatively because they tend to be one-beat, shallow puns. Ones that could be understood by a six-year-old, so when your dad is still telling them when you're ten years old (or twenty), you roll your eyes.

I think the problem is judging them. Some might find them shallow and some might find them clever. Or maybe it's people shouting "dad joke" at every pun anyway.
