As we all know, musicians are wealthy fatcats and developers are poor starving artists. When has Apple contacted developers to increase the size of its cut? Amazon claims to match Apple's 70% but in fact charges book authors for download size and halves your 30% for books over $10 (which is ridiculous given expensive books should have higher margins). When has Google informed you that you can opt out of having ads shown next to your content in search results?
