So...eBooks are selling fine for several years at one price, and then, for no apparent reason at all, the price increases 50% without any explanation.
Perhaps a little civil disobedience as punishment for unrestrained greed is a good thing?
And can we please stop calling it stealing? If my friend won't spend $700 for Photoshop, but then downloads a pirated copy, how exactly is Adobe harmed? They weren't going to make the sale in any case at that price. Yes, I realize my friend is unfairly enriched by getting to use Photoshop for free, but there's an easy way to curb piracy: make the product affordable. You reduce piracy, and you make up the lost revenue in greater volume.
That's what Apple did. By forcing music tracks to $0.99, Apple made them so inexpensive that many pirates didn't even bother to steal them any longer.
People and corporations have a right to protect their intellectual property, but there may be consequences to appalling greed.
The interesting point is the effect over the business model and approach to product management.
To produce the product costs X, so X < V*P (volume*price). However the concept of a "premium" product is based around a high price and lower volume of sales. It's a differentiation mechanism - works for Apple.
The fun comes when you've discounted the price so much that the margins fall (cutting into the cost) and you find yourself in a situation where you cannot continue to develop the product (regardless of the number of sales). All powered by a vain idea that you can crush the opposition by undercutting their price so they fail.. everyone hurts when a price war occurs.
The technique of dropping prices and starting a price war is how Wall mart and others conquer large areas at the expense of the folks making a living.
So in the end you end up with crap being sold because the returns cannot justify the development costs. Then you'll be left with a low price offering and a few high price that actually work.
Next the price sensitive people see the crap that exists and eye up the proper product funded by a proper business model. They don't want to pay for it so they pirate it..
The first rule of pricing - if you've got to the point of discounting to get sales or you're about to get involved in a price war then you've lost. Get out of the segment or redefine your strategy (put prices up and become a premium service for example).
In the end your friend is using the software without contributing to it's development. Without other people's contributions your friend wouldn't have the package. They developed the product, so they should have the overriding say in what happens to their product.
The only thing stopping your friend from pirating is a sense of wrong and right - to quote Oscar Wilde "Morality, like art, means drawing the line somewhere.".
