Nestle vs palm oil-free? Ethical choices

In the recent spell of hot weather I found that Rowntrees Fruit Pastilles lollys are palm oil-free. Having previously been limited to Calippos, which I really love but feeling like a change I was left with a moral dilemma.

Should I buy a Nestle product (which I have been avoiding since I was a child) that is palm oil-free? Is it going to encourage a company with questionable ethical history to make me palm oil-free products or am I using it to salve my conscience? Or should I allow myself to have a treat that adheres to the largest of my ethical concerns understanding that you cannot, in this place and time, live a completely ethical life and that by making myself guilty about every purchase I am not helping anyone?

So in the end I bought it (and one for Aoife) and I enjoyed it in the sun and allowed myself to relax for an hour before getting stuck into some new exciting monkey projects!
