> Google's customers are the problem, not Google itself. Kind-of? Ultimately, Google's customers are relying on Google's own filtering methodology. That's normally reasonable -- for the vast majority of people the spam filter works (from the recipient's perspective) so often that the spam folder is rarely even checked for false positives. However, Google has a scaling problem as noted by Brad Long later in the linked thread: linear scaling of human effort is too costly for them. That ultimately means that Google's services are offered on a like-it-or-leave-it basis, but leaving is made harder by the integration across the whole "Google ecosystem."
