No palm oil is sustainable. I have lived in Malaysia and can tell you that most the five hour drive from Kuala Lumpur to Singapore is spent looking at palm oil plantations. Malaysia is in fact with Indonesia by far the worst offender when it comes to deforestation. Also both countries are highly corrupt. Land grabbing is the norm and politicians and businessmen gain from the losses of the people in villages and the animals in the jungles that once were there.
Depends on what you mean by "sustainable". I agree that Johor has already been turned into one giant palm oil plantation, but as far as I know the current plantations can keep operating pretty much indefinitely, and peninsular Malaysia is not stripmining its national parks and remaining virgin jungle the way Indonesia is. (The Borneo side is a bit of a different story.)
Sadly, I don't there's a way to directly link to the product description, which is really silly, but allows you to explore some other things they have. Their Vanilla Almond Butter tastes like cookie dough. In a good way.
The subject was that palm oil involves dead orangutans. Does sugar frosting do that too, or are we changing the subject to how sugar is bad? If you overeat sugar frosting, it's your diabetes, not a negative externality.
Diabetes in a modern technological society with socialized healthcare (and all modern healthcare systems are to some extent socialized) does impose negative externalities.

So you can enjoy your Nutella guilt free.
