I believe that Microsoft expects this negative response after a big change (but they don't care). Their vision for computing is set in the long-term view. Those who do like it will not say anything, those that do not like will respond right away and then fade away. This is like the IBM attitude of the 80's-We are IBM, you will meet with us now, and we will tell you how you will have it done.
Microsoft is such a behemoth that a few thousand dissatisfied customers are statistically not significant to their bottom line and shareholder's dividends.
Microsoft does not care about the customers that buy their software-they know better than us. This unilateral change is the latest example of this attitude from Microsoft. They do not listen to customers. They don't want to give customers options. They just do not care.
