A friend of my wife's used to work for InBev, beers brewed under licence are either made industrially to the 'original recipe' (which likely didn't specify fifty hectolitre tanks) or simply supplied as a concentrated wort which is brewed locally using standard yeasts etc. So nothing much like the original. In some cases they don't even brew, they supply a ready-to-dilute concentrate – export Guinness stout in West Africa, for instance, is supplied as a dried flavour extract and diluted with local brewed sorghum beer.
I used to quite like Goose Island IPA back in the day, and their bar was in a rather scarely derelict couple of blocks of north Chicago where you could imagine being eaten by feral sewer people, but now it's a mostly generic and left behind beer. They used to do some fantastic beers (Night Stalker, an awesome stout) then they got bought out by Anheuser-Busch InBev (the corporate car-crash name tells you everything you need to know) and well, now they produce vast quantities of their dullest beers for the international market.
Though, for the record, Greene King IPA is probably one of the worst things I've ever tasted.
