I must disagree with this. When people are trusted, they tend to be more honest. But when they treated as potential thieves, they tend be more dishonest.

Let's take the vegetable/fruit department in a grocery store as an example. In some cultures the customer is trusted and he can himself weigh the product and put the price sticker on it. On other cultures the customer is distrusted so he is not allowed to do this in an uncontrolled manner. The interesting thing is that in those places where to customer is mistrusted, they seem to behave in a more dishonest way when an opportunity arises for it, compared to the places where the customer is trusted. Sure, there will always be those who will stick an extra apple after weighing them, but the cost benefit of not having any extra checks in place outweigh the losses caused by these few who behave dishonestly.

Now I believe the same applies with DRM. Will people stop paying for products as soon as they found out that they are not protected and can be, technically, freely copied? Some, no doubt, will. But how big of a percentage of potential customers will it be? Ditching DRM does not necessary reduce sells. Look at the music industry.

Anyway, these are only my personal opinions. No need to take them too seriously.
