I think they've been partly owned by them for a while.
They have, through ABInbev's stake in the Craft Brewer's Alliance. That was really about distribution, though. The big guys have Illinois tied up pretty tight and you only see a few craft brands in grocery and convenience stores, which is where your casual beer drinker is buying beer. It's quite a contrast to go to the PNW and see all those local beers at Albertson's or Safeway.
I'm taking a wait and see attitude on this. John Hall is still there but his son Greg, the head brewer, is leaving. OTOH, they'd already dropped my two favorite beers, their Nut Brown and Oatmeal Stout.
