It is a problem; that's why they put dates on them. You claimed it's for marketing, and it's not. Wine in supposed to be aged, most beers are not (sours and stouts are the exception). It's like eating day old food from a restaurant and pretending that's how the chef intended it to taste.

I've had almost every year of abyss going back to 2011. You picked a beer and a style that is intended to be aged, and the flavor changes over time much like wine. That has nothing to do with Budweiser, IPAs, pilsners, etc that are not supposed to be aged.
