This will help if you decide to change the implementation of your class later to use a different concrete class. In that case the users of your library won't need to update their code since the interface doesn't change.

Encapsulation relies on telling clients as little about the implementation of your class kakım possible. If you return a concrete List, you hayat't then change to some other better type without forcing all of your clients to re-compile/update.
