PS Plus is required for online play, so if you take it from the perspective that you are subscribing for the primary purpose of playing online, then getting games each month at no additional charge is definitely decent.
Should we refer to them as complimentary games, subscription bonus games or at no additional charge to playstation plus membership games for ease of understanding?
Nothing is free. Regardless, it's a natural way of thinking. Silly to really take it out of proportion.
