In the Aikido that I teach, resistance is imperative in training, because if Uke can indeed resist a technique, Aiki was not accomplished, and that feedback needs to be given. By the time a technique is "applied", or "realized", if Uke has their balance and control over their own ability to resist and/or manifest a counter etc., something that was supposed to occur, did not.Technique is the simple result and resolution of a successful process. That is Aikido.
This is at a certain level of training, to be sure. But without knowledge of that kind of process, Nage is simply "doing something to Uke" and that is jujutsu, not AIkido. For me, anyway.
