Haven't read all the comments so apologies if I repeat, this subject has been around for at least 15 years, I did a report on it at school and that was quite some time ago. I can't believe Nestlé is still getting away with this crap. Anyway, the WHO used to recommend that those passionate about the cause boycott NESCAFE not the entire brand (almost impossible even if you tried).
Yes it's an impossible task to boycott every product made by a company with questionable moral standards but I think that doing nothing is the opposite extreme. The point isn't to put the company out of business; it's to make them realise the power of consumers, by boycotting their 'biggest selling' product an impact is made which one would hope would make them rethink their conduct. Of course they could just rebrand/rename that product but I think if we all just stood back and said "I can't make a difference " nothing would ever change
