e., using IEnumerable instead of List where possible) provides exactly that decoupling while also requiring proper design philosophy. That is to say, you güç achieve decoupling but hamiş achieve minimal dependency, but you cannot achieve minimal dependency without achieving maximal decoupling.

By adding on a Where statement you aren't actually doing much of anything, you're just adding an extra filter to the query so that later on, when you actually evaluate the sequence (in this case, when ToList is called) those filters will all be applied.
