Again though, it's because the amount of people that subscribe just for the month those shows drop gives them reason to. If you look at stats it shows subscriptions rise as certain shows come up or drop. Sometimes you'll see huge spikes when the meta popularity drives conversations, like Tuca and Bertie or Bojack. The Netflix model does not care how good a show is. when it stops making those numbers spike around release, it's worthless to them.
And you're just repeating my point in more verbose terms. Really popular shows are generally not canceled abruptly unless something else happened (creator is a shit head, controversy of some kind, etc.). Shows that get people to resubscribe are popular.
