If you're interested in boycotting big corporations, may I suggest Boycott Buddy and Import Yeti as resources?
Boycott Buddy tracks all the various brands owned by a given corporation, AND provides a nice little summary of why you might want to boycott that brand in the first place (with sources!).
Import Yeti is a little less intuitive, but it tracks company supply chains - who are they buying from, and whose buying from them.
