Your point is just a technicism.
What people are complaining about when they say that there’s “no endgame”, is that what has shipped as “endgame” is just a boring and unrewarding waste of time by people that has no clue what makes the series fun.
And you perfectly know that they mean that when they say that there’s no endgame, so intendedly debunking fair criticism because of a criticism has a name: boycotting.
