Uh yes, exactly?
Clouds give small customers the first hit free as a loss leader. With very large customers, clouds have to be price competitive because if you're at a large scale, it is totally worth spending millions of dollars for a 5 year plan to change clouds. The people who get screwed are the medium to large customers for whom the cost of changing clouds is too high to recoup in a reasonable timeframe. The moral of the story is be very small or very large, but avoid being medium sized.
