Yeah sure they do but they are usually still complete and playable without , Ive completed Spider-Man , god of war and red dead without a single patch
The point is it's nice to have a complete experience on disc, regardless this particular case is being blown waaaay out of proportion because it's just a small ending to advertise another title in the future not the actual "ending"
I'm sure there's going to be a goty or complete edition in a year or so as per usual square, maybe even a next gen port complete , who knows
