I see what you're getting at, and yes, their consistency is the best in the world. I would say this more in terms of them being able to get the beer to taste identical despite being brewed in Newark, NJ or St. Louis, MO etc. etc.
There is little doubt that there's been drift in the profile of Budweiser over there years. There's multiple sources of this (here being one of them:

But that isn't to say it was a mistake. They make the beer they want out there - which is more to the heart of what you were saying.
But one thing that AB was famous for was never compromising on their raw ingredient quality. That is no longer the case. This drift, if it were to happen, would be imperceptible from batch to batch, and possibly even year to year. But over time, the overall quality of the product would reflect the change in ingredients. This was most famously demonstrated by Schlitz, when the beer essentially collapsed due to years of cost cutting on process and ingredients and led directly the the bankruptcy and sale of what had once been the best selling beer in the world. Google "The Schlitz Mistake" for the history of that debacle.
So getting back to Goose. I have no doubt that the QC is there, and that the brewery is putting out the beer as they want it to be. But are you going to tell me that Goose IPA tastes like it did 5 years ago? That beer is a shadow of what it used to be. 312 too for that matter. Ironically, they can now use the medals that beer won in its heyday to sell the current product.
