I wrote the article and you nailed it. In another comment I mention NumPy's ndarray has 15 attributes but 50 methods. Imagine the reverse, an object with 50 attributes? Even if the attributes were just booleans, that object could be in one of 2^50 different states! That's trillions upon trillions of states. Yes if attributes are global variables for the structured program that is the object, then the complexity of that object is very sensitive to the number attributes, but adding methods is mostly harmless. New methods are just new useful things you can do with that object, adding more methods does not degrade the existing methods, except maybe as far as discoverability and documentation. An object with a 1000 methods would be a challenge to learn.
