Ceasing to buy a product because they were bought by a major company makes as much sense as the dipshyts who were callng on everyone to not buy gas on the 15th.
It will make no difference to anybody but the hardworking folks at the brewery who may (but not likely) suffer from lost revenue from you. I am sure they will understand when you pass them in the unemployment line.
Before you start proclaiming cheapened ingredients remember you are talking about the best brewers in the world whose product has nothing to hide behind except their skill.
The reality is, if you didn't know they were purchased by InBev, you would never know. Now that you do your palate is tainted.

I don't drink mass produced American Lager because it is crap and its taste offends me but that has never stopped me, nor will it, from enjoying a beer that happens to have the financial backing of an umbrella.
I wish I had as much time on my hands as you...
