You miss the point.
What does it matter if the disc "contains the full game", if anyway you can't start playing it until installing/downloading more data? You're still requiring more than just the physical media for playing.
Developers of NBA 2k18 and Nintendo could have lied and said "a mandatory day one patch install is needed before playing", that way, none would be arguing because of this, right? Because we wouldn't think we are getting only "a part of the game", and think "hey, it's common to have day one patches these days, no worries".
