"Craft" has nothing whatsoever to do with the size of the brewery. They may cease to be considered "artisanal" , but still be a "craft" beer.
Actually, they're not very high on my list of craft brewers to begin with, but that's just my opinion. They do have a following, hence, the aquisition reports. Kudos to them.
But really, with the bigger brewers reaching back to tradition and beginning to make beers of more character, the term "craft" is becoming a bit muddled.
"Craft" doesn't (and shouldn't) apply only to small brewery product.
