I actively avoid Cadburys after Kraft took it over More Info. Wouldn't say it's a full boycott, because I do have a Crunchie every now and again (when Cadburys is the only thing on discount), but it has been more than 10 years now.
Thing is I just bought a box of miniture heroes and I'd say the chocolate has gone seriously downhill since I stopped buying it. Wondering if its just my taste that's changed or if anyone else agrees?
Agreed about the data farming, but I would recommend reading this if you haven't already. Not properly implementing the conventions is basically step 1 in that article.
