I'm a whiskey person (I drink a lot of rye) and I'm not intended to disparage the distilleries because of their parentage. I think a lot of them got rolled up in the 70s and 80s. Heaven Hill and Sazerac put out some pretty great stuff.
Edit: given the Wondrich reference further down it seems that you are. I've decided that cocktails have an appealing relationship to programming: they're arcane procedures that require specialized knowledge, but unlike software they're done in five minutes and they make you drunk.
I don't avoid it because of, it's just a nice added bonus to the drinks I like (the likes of Talisker). Just the same as I use gmail because I think it's the best option, but it makes me happy when Google do stuff like support LGBT rights :)
In fact, a lot of them are owned by the same big companies. A lot of scotch is aged in used bourbon barrels, so owning bourbon producers makes a lot of sense for scotch producers.
