Answer
Unmodifiable views prevent modification but can reflect changes to the underlying collection.
While unmodifiable views prevent direct modification, they can still show changes if the original collection is altered. In an e-commerce context, if the internal list of products changes, clients using unmodifiable views of this list will see these updates, which might be undesirable if you want a snapshot.
